(bright upbeat music) - Welcome to the "DL." I am your host, Tyler Robertson, the CEO and founder of Diesel Laptops. And if you're watching on the video portion today, you'll notice we're not in our studio. We're actually in Dallas, Texas at HDAW. So, we're doing a couple episodes from here. And I wanna say, it felt really weird.
I was inviting some people, calling people, texting people saying, "Hey, would you like to come to my hotel room?" I got a camera crew, and, you know, inviting some random dudes to your hotel room, could get weird, but this is not gonna get weird. So, I'm gonna say Vince with IPD, welcome to the "DL" from HDAW. - Hey, thank you, Tyler. Yes, if there's noises in the background, are probably cows, if you hear anything, that's some Longhorn running around.
- Yeah. So, you know, let's just do this first. Like who is IPD? 'Cause I'm gonna be honest. I was on the floor yesterday, I'm talking to different people.
I would say about a third of the time, the people I talked to, knew who IPD was, 2/3 of the time they didn't. I think it's kind of common understood. There's vendors, I was walking around with like, "Who are those guys? And why are they got a 40-foot booth? But those companies are here. So, who is IPD? What do you guys do? Okay. So, IPD is a company that's been around since 1955.
So, you know, newcomers on the scene. And we've been making engine parts for diesel engines, for, you know, big engines that whole time. You know, pistons, liners, rings, head gaskets. We focus on the hard parts. It's in our DNA, it's what we do. We dabble in some of the smaller engines, like a six-liter engine, but for the most part, it's the 15-liter and up stuff.
- So, it's truck and off highway's a big part of your business too? - Yeah. Truck's the smallest stuff we do, right? And most of the stuff we do is bigger. It's pistons that, you know, are so big that you gotta use a forklift to move 'em. - So, how does a company even get started to say, "Hey, I'm gonna go build big after-market engine parts? Like, is there a founding story? - Yeah. I mean, it's one of those, it's before my time, obviously, but it's one of those companies that started in a woodshed. Bob Rasmussen and Walter Storm many years ago, founded the company, making, small parts for a customer who needed something.
And you start with one part, and then you just start to make additional parts. And when you start to put together the expertise around, okay, how do I make something like a piston or a liner? And then you start to put, okay, how do I ship it? And all those things, you learn those things as you do 'em. And you're like, look you know this from starting company, it's like- - But what's amazing is how many parts companies I talk to that have a very similar story. Someone years ago was like, "I need a widget for my truck."
And nobody makes it. - Yeah. - Or the manufacturer stop making it, so I'm gonna make it. And then they sell it to a buddy, and a friend, and here they are years later. And IPD is not just a North American company, that's the interesting thing about you guys, it's really a worldwide thing where you guys are. Where else do you guys put these engines in? Yeah. The U.S, I'll say how about,
you know, north America, U.S and Canada is only a little more into 50% of our market. The rest, they go all over the world. We've got locations in Australia, in Europe, and Denmark. We have sales guys located in places like Poland, and Russia, and, you know, the Middle East, and it just goes on. I mean, it's every continent other than Antarctica, we've got boots on the ground.
- Yeah. I mean, that's just crazy, right? Like people look at diesel engines, and they're really the same, no matter what continent they're on, at the end of the day? - Yeah. They're the same. And it's the people who make them, the EOs, right? You know, Caterpillar, Cummins, whoever, Detroit, they leverage that global economy, right? They make it, they design an engineer in one place, and then they sell 'em everywhere. So, the aftermarket that people making parts, replacement parts, which there's an important distinction between making an aftermarket part, a part that'll fit, versus say, making a replacement part. Because when you're rebuilding an engine, that's been rebuilt three, four or five, seven times, the part that goes into that engine might not be the same part that, or it might not be the same part that came down the assembly line when that engine was new.
- Yeah. I gotta imagine when things are new, when things are tight, and everything's machined to fit inside each other, but things wear now and after a 1000, a 1 million mile, 2 million miles, 1000 hour, you know, whatever metric that's being used. - Yeah, and when you start doing things like, you know, taking, 10,000s off ahead, suddenly gear lash starts to become an issue.
Things that wasn't an issue when you put the engine together new, it's now an issue. - So, how difficult is it been? You know, 'cause I come from the repair side, right? So, '04 we added the EGR system, and then we added DPS systems, then we added SCR systems, and it just goes and goes on and on. Has that added a lot of complexity to aftermarket companies such as yourself having to kinda keep up with new engine redesigns, and these things that are happening inside engines? - Yeah, for sure. Particularly on highway, right? So, in the off highway world, there's still a lot of engines that run like they did in 1992.
Okay. So, you people keep rebuilding. You'd be surprised that there's still those old two-stroke Detroits that are around and people just keep running those things. You know, after treatment, really it's more than just the way the engine runs, it's the electronics of the engine. And you go from a little pump line nozzle, diesel system with a mechanical governor. And suddenly, now you have an ECU, you've got an electronic control on it, it's just a different ballgame.
- Yeah, and I didn't understand it 'cause I worked at dealerships forever. So, I always saw the new stuff, right? And dealerships typically don't get the old stuff. And then, I had a chance to go up to the Yukon to see on the scene of "Gold Rush." And I can tell you, they had nothing new up there. (laughs) And they were rebuilding old Detroits and Cats.
If they could find a Cat engine in a truck, it was like literally that was the thing everybody wanted up there. 'Cause they could just rebuild the things forever and ever and ever. - Yup. - So, I totally get it. So, I guess let's kinda talk about the future. We talked about the past a little bit. - Yup.
- The interesting thing, is I believe you guys launched a new division in your company? - Yes. - I would love to... You get a new title? - Yeah. At IPD, we're always striving to be innovative, right? And do new things, and, you know, come out with steel liners for the ISX. We came out with that a few years ago where... I don't know if you know the ISX engine, where if you end up throwing a piston and seizes, or the things start to wear out, you can very easily throw a rod through the block.
So we came up with a steel liner because we said, "Hey, you know what? We need a liner that will contain a piston coming apart." Which it did by the way. (panel laughing) And normally, liners are cast iron, right? But we made it out of steel to try to innovate. We also have cryo-treated head bolts, right? So, Cat C-series engines are notorious for having head gas issues.
And the problem, is that the head bolts are just not strong enough. So, you take the same head bolt and you run it through a cryogenic treatment process. And now, that head bolt is strong enough, and it torques- - It sounds like fancy futuristic stuff almost? - Yeah. No, no, it is- - It's cool to hear though, like, Hey, there's an OEM made something, and you guys are like, man, there's a high rate of failure. We're gonna figure out a way to make this thing even better the second, third, fourth time around, which is great. - Yeah. And look, it sounds cheesy, right? 'Cause you say, "Oh, it starts with the customers."
But it always starts... You know, there's a customer involved, right? You don't just sit there and think, "You know what? What am I gonna do today? No, there's always a customer who says to you, "Hey, I have a problem." And sometimes the customer say, "Hey, you've solve it."
And other times, you know, you have to figure it out. You have to spend time with your engineers and, you know, the smart guys. As the world changes, and as engines went from being mechanical to being electronic.
And then as the internet became alive a few years ago, the ability to talk to an engine controller went from nothing. You know, the engine controller say, now having the ability to, as you well know, hook a laptop up to a machine. So, from very general perspective, IPD launched a new business, that's called IDS, Industrial Digital Solutions. And it's here to attack some of that, the internet... What is it called? Industrial internet of things. So we're looking at, okay, how do you take a device and connect it to telematics, connect it to the internet, connect it to other devices? How do you connect it to your operator? And how do you do that in a meaningful way and simply? - Yeah. You know, I think a lot of people too,
I don't really understand what you were saying, about the reason these things are electronic, is we needed to control things, and things are getting more fine tuned and emission. Like things had to go that way. And I know people complain about it a lot. So like, "All that computer that's the problem on the truck, all these sensors now, why don't they make 'em like the good old days?" You know, those days are long gone and never coming back.
And it's created a lot of complexity. I mean, that's why my company exists, is because things got really complex, really quick to fix, and people need diagnostic tools to do that. So I'm starting to see in your industry, in the aftermarket world, which we're both in the aftermarket world, just in different areas here, you need the ability to know when your products, especially on that vehicle, like what's it doing? What's going on? How do we stay competitive and make sure we keep making better products? And all those things. So, why don't you go ahead and talk about, hey, we have a product that we're helping you guys with? So, let's talk about that a little bit. - So, from that IDS, right, from the concept of saying, hey, we're gonna do something that's so radically different from our core, we're gonna start new business. And that was the point of starting the business, was that it's so different from what we normally do.
Now, of course, when you do something that's so different, you can either sit there and hire a 100 people, and all try to figure out how to do it. Or you can partner with someone who's intelligent, and has already done it. Which is what we did in this case, we said, hey, (chuckles) help us out with this. And so, the product that's called Truck RX, you guys are providing the the backend and the technology.
you know, very similar to a Diesel Decoder where you can hook up into the J engine 39, the diagnostic port on an on highway truck, and then talk to the machine. You know, you pull your phone out in the same way that you can buy a refrigerator and you can ask that refrigerator what temperature it is from your phone. The stuff we can do, like you know what kinda food's in your refrigerator, right? People have that, right? The future's here, right? We don't have flying cars yet, which I'm really disappointed on, but we do have refrigerators that can tell us if we need milk. Well, you're on highway truck now, is trying to tell you things. Okay, but if you don't know how to listen to it, a light's gonna appear, and you're not gonna know what that means. In a very simple sense, the Truck RX product is here to allow an operator to talk to a machine in a way he couldn't a couple of years.
- So, you're this 65-year-old company making hard machine parts. And then, all of a sudden, someone in your company, I dunno if it's you, or some people in your company who are like, "Hey, we need to get some technology here." Was that a big transition in a conversation? I gotta imagine that's difficult. You do one thing forever, and now, it's we need to do this other thing. How is that internally inside the company? - Well, okay, look, so it always starts with, you know, some, some idiot, right? You know, and I was one of those idiots.
And there was a few of us who said, "Hey, we wanna do something that's bit different from what we're used to doing." And then, going to the board, the directors, the owners of the companies and saying, "Hey, we have this idea, and this is what's gonna cost." - Yeah.
- And then, they kinda look at you, like are you sure about that? - If we need a bunch of money. (laughs) - And you see, you don't know, really this is gonna be fun. It's gonna be exciting, you know? And it's the future.
Even something like engine parts, there's gonna be... There's a long tail on the internal combustion engine, right? Its demise, you know, pundits are always saying, "Yeah, it's going away." And all the passenger cars are being outlawed. On the highway truck side, on the commercial side you know, engines, machines that do work, dozers, they're gonna be around and in a very similar state to what they are today, for as long as I'm alive, okay? - Yeah. - But at the same time, the way that people interact with them, via telematics.
So, every new machine and every new on highway truck that's being sold today, has telematics that connect it to the dealer, right? The OE dealer. And the OE dealer gets all this information about how that truck is running. He can use that information to go to his, you know his customers and say, "Hey, you know, I can help you make your trucks run better." And so, that's what we're trying to do. And we're trying to provide the information also, not just to... You know, so the dealer doesn't get it now, the independent aftermarket can get that information.
- Yup. - And that's something that is gonna be very powerful in the coming years. - Yeah, I didn't realize it was in the data business until about two years ago. And I'm like, "Wait a second. I'm on the business of efficiency and diagnostics. I'm the business of collecting data.
- Yeah. - And you're right. Because people and companies like you, you need to know when your products installed in a vehicle, well, how's that vehicle operating? And you talked a little bit about predictive, right? I mean, everything that happens in the world today is reactive and it sucks. - Yup. - Because, oh, something's broke, my load can't get hauled. When can the shop fix it? I gotta find somebody. Can they find parts? Like all these uncertainties happen.
And if you can actually get to predictive, now you can plan for things, and it changes how people can run their business for the better. - Yeah. Yeah. There's an expectation that an engine will run for certain number of hours, certain number of miles when a guy rebuilds an engine. And being able to prevent these catastrophic failures, which, you know, look, we've all seen the engine with the rod coming through the block, and, you know, you that's bad, right? And so, and as a company that makes hard parts, it happens, right? An engine built by with your part sometimes go goes boom.
And you kinda look at it, "All right, you know, let's figure out what happened." And you're doing all this... You know, you're looking at the engine trying to figure out, okay, why did it fail? What happened? But the ECU has all this information in it about how it was running and knows thing before they happen, all right? Because it's got sensors, right? And so, your ability to take that information and predict things before they happen, predict check engine lights before they come on, understand your fuel injectors are floating even before it gets to the point where the engine says, hey, there's some me wrong, it's huge.
And then doing, not just on one vehicle, but now you've got 10 vehicles, you've got a 100 vehicles, you got a 1000 vehicles. That's where you can start to pull information and comparing. The simplest example I give to people about how do you save fuel economy with one of these devices, is that if you have fleet of trucks, and you have a different driver gets a different truck every day, you can then look and see, okay, what your drivers has the worst fuel economy, right? Because one of them is gonna, you know, we got a heavy foot than the others, is gonna shift differently, he's gonna do something weird, and maybe he needs training. Or you're gonna have across my fleet, all of my drivers have the same fuel economy but that one truck, gets bad fuel economy, and that's costing me money every single day. - Yeah. I mean, if you can't measure it,
you can't improve it, right? I could say my business, like it's amazing how many times you find something and we're like, "Well, what is that measurement?" You look at like, man, that sucks. (laughs) And then you go make a little tweak, and all of a sudden, things are better, right? But you to have data, and you have to have the insights into those things. So, you got this new division of the company? - Yup. - We got Truck RX that we're working on, coming out soon.
- Yup. - I'm assuming you're gonna have more than one product eventually? You guys have some big ambitions here and some goals. - Yeah. So for us, look, there's...
In the world of, I'll say, you know, telematics for, you know, even you pick on highway vehicles, there's the really expensive, complicated OE solutions, especially for when you get to the machine side. And then there's some of the stuff that's sort of, like, I'll say telematics light. Okay. So, you know, it hooks, it tells you where your vehicle is, and maybe it tells you the fuel economy. Maybe it tells you if there's a diagnostic code on it, but it doesn't really give you information on how to repair it, or what that means. It certainly doesn't connect it to a service, a service guy, right? It gives you the data, right? And so, if you're an owner operator of a small to mid-size fleet, you're kinda today in the world of telematics, you're kind of screwed.
You don't really have any good options that will tell you how to fix it, connect you with a service guy. And so, we're trying to build that infrastructure to say, look, you know, in your small to mid-size fleet management on a diesel engine, or a natural gas engine that's running down the road, you need to have information that can go to a service guy, multiple different service guys. And, you know, look, we're starting with a device that's gonna save you money on a tow, right? One dealer diagnostic fee you saved on when you do something on a Truck RX. But the future is gonna be connecting that into the cloud, having multiple different devices being able to talk to each other. And then, the off highway side of the world, which look, that's our on highways, maybe 20, 25% of our business today.
So, most of it's on an off highway machines, and then it even goes to Marine. Each of those set requires a different set of technology, and there's regulations around different engines, and the way you have to even talk to them. And I dunno if you've ever looked at what the equivalent of the FCC is in places in Africa, right? - You know, I haven't. Do they have emission laws and things like that? Every country has their own rules about what you can communicate, how you can communicate? What kind of data? Where you can store the data? - Yeah.
- You even just go to Europe and I find there's GDPR. Britain moving out, you know, Brexit, now they have different rules. And so, you have to know those. And so, each one of those markets is different, but there's a ton of opportunity because when I've gone and talked to customers and said... You know, IBD customers who have been buying hard parts for years from us and said, "Hey, we have this idea, we wanna create this business and do this."
They've always said, "Fantastic, when can I have it?" That's where I was saying, "Okay, slow down. we're not there yet." We need to develop the technology and make it happen. - It's really good to see it come company, though, that's been around for 65 years saying, "Hey, we need to understand this stuff and use it for our business." I think that's just a growing trend industry in general.
I know we compete against the OEMs with our tools, and the things we provide. I mean, I knew you guys do as well. So, I think we look at the same way, like, man, they got all the resources, they have all these stuff. We need to keep innovating and keep coming up with new products and services, so we can go compete. I think your company's doing a great job as well, because, I mean, let's face it, you have people that sell overall kits.
You guys sell overall kits, right? And you're creating those differentiators and those value ads, but all of a sudden you're competitors gon' be like, "Oh, what the heck? Like, how do we compete against that? We don't have a company." You know, like you're building that wall and that model around your business, which anyone listened to this that owns a business, needs to figure out how do I build that model? How do I build hard walls in my business so people can't compete with me? And now, I can charge a higher premium price. And now, I can do these other things because of all the values we provide. So, very similar business model that you're doing with this is exactly what do at Diesel Laptop. - Yeah, well, and look, as you know, it starts with smart people.
I have some really smart people on my team. In fact, an engineer right now who's installing, or actually has already installed a beta unit on a machine, running a diagnos with our machine RX. It's our next.... It's the expensive, complicated product, versus the simple truck RX product right now.
Yeah, you have to do things that's outside your comfort zone. It's not what you're used to doing. You know, you have to go to the board and say, "Hey, I wanna do something crazy." - And I need a bunch of money.
- Yes, and I they spend a bunch of money. - I can't tell you what we're gonna get for it, right? - Yeah, exactly. And then sometimes you gotta throw it against the wall and see what sticks. - Yup. - And then you gotta work with other people who are similarly, sort of innovative and intelligent. If you end up spending your time and you're dealing with the same suppliers, the same allies, the same buddies the whole time, and yeah, you're not gonna grow. Your business is gonna...
You know, their Moat's dry up, and your piece of land's getting smaller, and no one wants that in the business. - Yeah. Well, and I know, you know, we talked about that. I just wanna talk about one subject that's on everyone's mind right now.
And that's just supply chain part, parts issues problems. Obviously- - We don't have any of those problems. - You guys are perfect, yeah? - Yeah. - But, I mean, how? Is it getting better? I mean, I'm on Facebook groups, I'm on LinkedIn, we talk to customers every day. I can't find turbos, I can't find... There a point that people couldn't find overhaul kits for Cummins engines, and I think that's still a problem for some models.
Is it getting better out there? Is it worse? I mean, I know we're struggling with some things too, but how are you guys doing? - I mean, look, we've had some... This last year, it's been a weird time to say we had a good year, but we had a good year. We had a lot of people coming to us and saying, "Hey, I want parts. I want more parts." What we've really noticed, is that the people who are able to plan better and say, okay, I'm gonna need a rebuild kit in, you know, six weeks or six months, they're the ones who are making it happen.
And the people who come to you with their hair all shoveled, and be like, "I need parts today." - That's like 99.9% of the customers, doesn't it though? (panel laughing) That's exactly Truck RX is trying to fix. I get it but- - Yeah. But it's the people who are able to plan and know what their...
You know, when the maintenance is gonna be needed on an engine, when an overhaul. Because a lot of these big machines, are, you know, that 20,000 hours they get rebuilt, and you know the story. - You know, it's coming? You can put it on daily on the calendar. - Yes, there's a season for where they do the work. There's that seasonal aspect of rebuilding engines, you know, because it's...
Your gold rush town. They're not running the engines in winter, right? - No. - Probably not even rebuilding them 'cause it's too cold. So, there's a time where they have to rebuild it and they know when it's coming. And so, if they're able to say ahead of time, "Hey, I know that there's this supply chain issue.
I know there's this crisis that everyone's dealing with." which, you know, we are dealing with as well. "So, I'm gonna go, and I'm gonna ask for my parts a few weeks ahead of when I normally would, those guys are doing well, 'cause they're getting the parts." - Yeah, so I remember when COVID happened and people started hoarding toilet paper, and then groceries. Are people hoarding truck parts? Is that a thing that you're seeing do now? - Stocking. Look, some of our distributors are rebuilders and some of 'em are stocking distributors.
And the stocking distributors are doing better because they're even selling... We've heard about inter distributor, like one that sells to the other guy, and it's just, okay guys, you know, you just- - There's always so much to go around? - Borrowing, trading, and the people who were a little bit more from a business perspective, it's always nice to have that thing where, you know, I utilize cash well, right? You know, inventory, you know, I'm just the king of, you know? - Yeah, just in time, manual inventory. I'm turning inventory 10 times a year. - Yes. - Those guys in trouble now. - They are absolutely.
And look, I came from the OE world, right? I worked with OE suppliers and big companies. And yeah, it was all about that, like the guys who were like, well, I can save a $1 million by, you know, $1 off one of each one of these parts that I sell. And then I can keep it off our books by having it on a supply chain that's really long and it's complicated.
Those guys are like hating life right now. - Yeah. - Yeah, and also it's also insourcing. It's the people who are able to do things themselves, are also, I think, are doing well right now. - Yeah, have you seen all the oil shortage stuff going on now with engine oils, and people not being able to find their brands and whats the going on? - No, I didn't know about that.
I did notice that the price of oil is through the roof. Like a can of oil for your car is like, is, you know, or for a truck it's nuts. - Again, I'm on a lot of Facebook groups with drivers, truckers, mechanics, and the technicians. And that's the thing I'm seeing now, people are like, "There's no more of my brand oil I had to use."
they didn't have... First it was, well, they don't have an in bulk, but they one gallon jugs. And then it was, they don't have my brand any more, and so now I'm on brand B. Like I can't get my Mobile, I get whatever off brand, or whatever.
And now it's like, well, that's out too. And people are hoarding. Literally people are like, "Yeah, I bought 50 gallons to keep my garage at home for my next four oil changes." And I'm like, yup, hoarding. - Hoarding. - We're just going through the same cycle over, and over, and over again, so it's almost comical.
- Yeah. I mean, there's to tires. Like I had a hard time, I was trying to get a set of Michelin tires, and they've been out for like six months, of a particular style and size of tires. And they're like, "Okay guys, what?" It's gotta clear up eventually because...
I mean, to get here, I flew out of the LAX, right? And to fly outta LAX, you fly up, and then you turn left, I was on the left side of the plane, so I got to see the port. - Actually, was there a couple ships out there waiting? - It's just this stack of container ships that's just as far as I can see, they're just there. And so, I took a picture from my supply chain guy to send to him- - So, I have the chief of the port of L.A
coming on the podcast here in a couple episodes. - Good. I'm willing to hit him up like, What wrong with you guys? I know it's not their fault, right? And there's a lot of reasons, so no. But, hey, it's been very interesting having you come on here.
And I think more than anything, I'm just really humbled and honored to be working with IPD. You guys have a great brand name in the marketplace, really excited, you guys selected us here as a technology partner on this first product. I know we're gonna deliver for you guys.
I know it's step 1 of like step 100 where both of us wanna get to. And I don't know if you notice, but it was almost two years ago to the day that I first met IPD, and even a more shady hotel room than this one, right? We didn't even have a suite, we just like, "Hey, ome sit to the bed next to me." And we kind of patted it, you know? And we had a conversation with some of the IPD people. And I know even more like Bob Straw even retired in the meantime, since that whole thing. So, it's been a journey, and it's actually good to meet you in person after doing so many Zoom sessions.
- I know- - It's almost weird seeing in person, I was like, "Oh." - Yeah, I think you or someone said, "Oh, you have legs?" I get it, "No, you have legs." Yes, I did, yeah.
No, and hey, look, it's the same. We appreciate working with people who are intelligent and people who are motivated, and, you know, know the technology, and wanna do something that's outside of, you know, what you do every day and make a difference and help the customers out. And we can see that, or, you know, I can see it in you that you wanna make those customers smile and make them happy in new ways, not just the same way, the last time that they were happy. - Yeah, hey, there's always a better way to do something, right? - Yup. - It just often takes a lot of money and time to go figure out, "Nope, either that was a better way or it wasn't." But we all get there eventually.
So, it's on what we do at Diesel Laptops. So, if people wanna get ahold of you, or learn more about IPD, where do they go? - So, for IPD, you go to IPDparts.com. but for IDS, we have a new website, so IDSrx.com is a website.
There's a contact form where if people want more information, they can put a contact form in there, and we will keep them in the loop as we develop these products. - Well, I'll tell you, a new division, new website, new product, new job title. - Yeah, I know. - You must feel like almost kind of starting fresh inside your own company at this point? - Yeah. Well, so I haven't.
I still have my old job, so it's just... (panel laughing) The chief technology officer job, it's just additional, it's just more fun. But it's fun, and I say with all honesty, it's just the most... It's exciting and it's fun, and it puts a smile on my face every day to jump into crazy stuff like this, - Well, awesome, man. Thank you for coming on.
Thank you for meeting with me. I know it's early in the morning here, we were all kind of out late last night. So, it's been great to get to know you. So, as we end every episode, it's just not diagnostics, it's diagnostics done right. And check out IPD, check out IDS, the new product Truck RX, I think it's gonna be a great thing.
