INSANE CUSTOM SEMI TRUCK! Built By Welder Up. 

Coolest Truck in the USA 🤘🤘🤘

The old Cat mechanicals are the best old engines they ever made!!

@welderup I am a truck drive of 25 years and grow up in the trucking world. That CAT is the best motor ever made. BUT at 2100 RPM YOU should be at 135 MPH to 157 MPH. YOU NEED a 18 speed at a minimum 15 speed for what your doing . With a 18 speed 1200rpm should get you at 90 MPH

I got my A license in October and I’m about to start learning MIG welding. Dude, your work is inspiring!

My first introduction to WelderUp creations was a featured diesel rat rod at a show in Vegas, but this truck was in the background and stole the show. I love the creations from your shop, but this one holds a special place in my heart. I have been driving Peterbilts all my life, the first being a 1961 narrow nose, butterfly hood, 5+4, and wedge brakes. Similar to the one from the movie "Duel." And this one speaks to me on a level most people will never understand. Even had one that knocked a hole in both sides of the block in a celebrities driveway. Beautiful work and forever a fan of the steampunk styles of so many of your creations.

Throw the crapper away and you can auction the truck. This is a master piece. A life's work 👍

You know its serious when even his welder has a turbo and nitrous😂

It’s very unique to hear that your a artist in this field with no tattoos. I also build custom cars and furniture no tattoos while my sister is a tattoo artist.

Steve, thanks for the video. As a long haul trucker, I appreciate your actually having knowledge on your vehicle. So many guys own cool shit but have no idea what is under the hood.

"If you're a crackhead, stay away from my truck" haha hilarious. COOL truck for sure!Dude you never stop moving! Keep up the great work!

You know what man, you've earned yourself a lot of respect points in my book by one thing. No TATOOS! Most guys and gals look like they've been hit with a wet newspaper. I salute you brother. Best to you, from South Africa.

I can honestly say everyone who works at Welderup are some of the most down to earth, most amazing and friendliest people ever. I went to Vegas a few weeks back for my birthday with my mom and the only thing I wanted to do was go to Welderup, I was telling the lady working in the showroom my story and she helped me experience one of the best birthdays ever, including meeting Steve and getting to ride in this amazing semi-truck. If anyone deserves fame or fortune hands down goes to ALL the Welderup crew! Thank you so much!

This has got to be my favourite of your builds. It says everything about your personality and that of welderup that's why I love the program so much. J

Only one word....COOL. Every Motor Head has their build in mind, that they drag around in their head for years, if that ever Materializes, beautiful stuff happens, and will never sell or Trade.

The thing I love and so appreciate is your level of creativity and detail. When I do builds I always want to do the same thing, so I know it’s not easy to always come up with new ideas and you do! Fantastic work Steve! Keep them coming.

Waiting for the jake break sound that never came :(

Was hoping to hear the jakes at the end. Looks like someone has been having fun on that road you were driving on..

I just saw this truck yesterday getting off the 95 freeway in Henderson, NV at Wagonwheel Dr. and even tried to catch it at a light to check it out some more. It is truly and amazing vehicle and I wish I could've been able to actually get down and check it out lol That this is 100% American Badass!👍

That's an ultra-bad-ass project / work truck. Very cool, thanks for the tour!

I've spent 20 + years building and Custom Motorcycles 10 + years driving a Freightliner. Got to say this is one of the nicest rigs I've ever seen, not overdone not gaudy.

This thing looks like the new enemy of Optimus Prime.

wow I just love it Steve Im a retired shop owner and trucker this truck is just insane 👍👍👍👍👍👍👍

I went all the way to Las Vegas from Maryland just to visit welderup and check out the coolest peterbilt I've ever seen and the d-rod. I purchased the d-rod hat from your gift shop and it's by far the coolest hat I have. Love it and love welderup.

Absolutely beautiful truck. The best thing about your builds is that they are well thought out. Everything is functional and purpose built. Not many builders can build something they can actually enjoy and truly use. This truck is simply amazing!!!

I can't say I've ever tried that shiting pose. I'll have to try it looks pretty fun😂

The movie “Duels” sinister Brother!!!! The rust patina touch rocks!!! One of a kind

Wow....... I've seen a lot of beautiful 379s in my day. But this... the paint, the welder, the hole... straight outa of mad max.

“Merlin is like a genius for making drivelines.” You hesitated in the middle. I really thought you were going to say “wizard” instead of genius. Hahaha

there must be about a thousand pounds of copper on that truck, it looks amazing

BADASS!!!!..How friggin cool...You've won the "wrench's dream"..Congrats!!

Love the brass knuckles on the hood!!! If I ever built a truck I would have to put the black duck like from the movie Convoy!

I’ve always loved seeing this truck being from Vegas and also being a diesel fanatic I love everything you do I can’t wait to go on one of your tours one day! Keep up the good content

I wish we had more of those in South Africa instead of the 362E. The 379 body style is insane, I love the attention to detail and workmanship on this build; as well as the ability to use it as a functional daily hauler. Congratulations man!

Steve your right the Peterbuilt is your most outrageous and coolest beast!

Even the welder has a turbo! I love it!

When my parents went to Vegas on vacation, they tryed to find Welderup. As they were leaving, they saw you guys were way out there in old Vegas. My dad said he wished he could of went cause hes one of those truck guys. He's drove a 18 wheeler his entire life. Whether it was being a logger or driving those big Cats in a coal mine he's just done it.

The truck gives you a feeling that you're back in The walking Dead

"They call it CAT for a reason".. Yeah Caterpillar..😎

Love people that dont give up on machines

Old truckers never die, they just get a new Peterbilt................Someone should make a horror movie around that beast............

Now that’s a truck for a mad trucker. ITS GOT A CATERPILLAR! Hell yeah brother

I wanna fly over all they way from New Zealand to see this truck. Love that oxidized copper look on the tanks too. Nice and clean inside, just how a truck should be.

33:28 I’ve driven many semis, you can tell it’s got air bags in front just by this footage, you’d be bouncing up and down right here if you didn’t! It looks like it would be a comfortable ride!

Saw this truck yesterday driving around near Placerville CA, badass truck

As a trucker I've always loved this truck and the 359 you built. Great to see what you've done to it. Love the old school steering wheel and also the heavy duty steers. By making it classified as an RV does that make it so you dont have to run log books and get your commercial lisence?

10 speed? Not an 18 speed? Mad respect for not going overkill, too many custom trucks have 18 speed, it's just a workout for no reason. Not unless you're pulling 100,000lb

I've slept in my 2001 Chevy Astro Van. I'm not tall so the backseat is fairly comfortable.

I work a peterbilt dealer and don’t think we have installed a sleeper. We have done a lot of day cab conversions though. I got see this in person at your shop in May. Video doesn’t give it justice.

One sweet truck! All the work in that truck amazing!

I remember the episode of it being built and thinking what an amazing truck with an amazing story

I never thought i would ever see such a cool truck im my life . Wow

Hell ya bro. Some of my best friends were Mexican. Some of the best most hard working people you could ever meet

“that being said if your a crack head stay away from my truck”. I died😂💀love dis man.

It is a freaking Truck, but if you step back and look at it, it looks like the coolest, biggest Pickup that i ever saw, great job !!!

wow!nice job man, that thing is epic! one of a kind for sure! talk about a head turner, traffic jam maker, so badass bro! love it

Wow,Steve what a vision turned to reality!!Trucks have always been a love of mine since a kid.Love it brother.Fan from Sydney Australia 🇦🇺 💪

I always love that beefy front tires, looks so damn good especially compare to regular truck.

First time I’ve seen a turbo on a welder 🤣😂 👍✌️

The coolest truck I have ever seen bar none!! You are a flat out artist my man.

“Never ending battle” to keep everything working! I feel your pain.

Great video Steve ,love the truck even more now than before. 👍

Coolest thing about this trick is that it’s a flat bed roll back. Now that’s what I call a car hauler.

I love how it shows you use the truck when the hood was about to fall off

Need a sound vid of just the exhaust for a couple minutes in and out of cab

I've seen this truck before and I still can't get enough of it . the color the fake rust it's just amazing. Great work my friend keep on keeping on.

Been waiting for this! Amazing truck! And glad i got to learn a bit bore about it!

I'd like to hear more about the turbo on the welder!

Most genuine guy ever. Awesome video, thanks for sharing.

Definitely a sweet looking truck, inside and out. Functional too, not some car built to take to car shows and up on stands in the garage the other 364 days of the year. The old ratty look is great on the right vehicles, this truck being one of them. The headlights were a great addition to the overall asthetics of the truck. The leather work is unmatched. All tied together amazingly. The story with the truck is a great addition to the video as well. Many hours of blood sweat and tears into this thing. Can see that. I've been messing around with vehicles since I could walk, but am getting burnt out on them at this point. Working on mine as well as other people's really gets to you. I'm at the point in my life where I don't even bother with vehicles from modding, fixing, etc for so many years. I was tossed into the automotive field because I had no choice. I tried getting out of it many times and always manage to find myself back in it. I think a lot of it has to do with I know vehicles so well and that I can't do some office job. Anywho, great job on that truck and am curious what else you might be working on. Maybe that old Dodge? towtruck I seen?

Very cool. Matte clear would also look pretty nice.

9:40 Just cause you're the first person to make them (assuming no one else did) doesn't mean they stole your idea lmao. There's a difference between a good idea, and a unique idea. They don't always go hand in hand.

The interior is not what I expected and I love it

I drive a 359, lost that same hood pivot bolt. But I promptly found it, luckily it impaled its self into the brand new super single on the right front drive.

This truck looks similar to one built by Diesel Brothers. Neat truck.

That truck is unreal! What I mean is that your work is so cool, it actually doesn't look real. Geezus!

Seen this in RENO hot August nights 🔥👊💪🇺🇸

Yes. It is really cool. One problem with the fake patina is the rust from the fasteners. The rust streaks go UP and down. How could they go up? Water runs down hill....not up. Still, it looks really cool. Also, a flat clear coat would have been more convincing. I know people like to put a gloss on a real patina. It's just my opinion.

I agree, the best motor ever built....easy to maintain and rebuild is easy. Awesome truck buddy.

The rig is stunning! and then you showed the interior😍. The 425 tires are sick and the paint is unbelievable!

This is by far my favorite big rig out there brother great job on this truck 🚚

I’ve been waiting for this, such a badass truck

Its an honest motor and low end.... Let me say it again a few more times.....

I'm from Michigan ✋ looks like Icicles off the roof of my garage ☃️🌨️ hahahaha 😂😀👍 Installing/picking up the bed THAT would've been an amazing video 👍🙏

b model is the best engine ever made hands down

Damn, that's cool. That roulette table lining is a stroke of genius but then again the whole rig is.

"I go camping with this" I like that this guy really dose use this truck! Seems to enjoy it a lot.

Going down the road, “balls out”, and taking a shit. Now that’s another level I need to reach. Lol

Looking at your pete brings back memories and wild times. thank you

That 3406 b model has a manual horsepower increase on it . meaning that each click adds 80 horses . I drove one that had been turned 4 clicks , meaning it dynoed at 740 hp to the ground . no bullshit

Ok we got to know about the Pete. Now I wanna know about the Diamond T!

It would be cool to fab a foldable boom for hoisting loads onto the deck. I appreciate the art on the interior.

Thanks Steve this was such a great video! Would love to see one like this on this diamond t!!!

7/30/23 Obviously been a minute since visiting this channel but DUDE! Nitros on a welder😁 Wish they’d had that before I retired. Wanna see what it does.

Glad you stuck to your vision & didn't let anyone stop you, despite what was said😎👽🤟🏿🤟🏿Pure motivation!!

Love the steering wheel and leather work

I saw this truck in Coolidge AZ at Stinger Bridge and Iron. Even cooler in person!

I swear I’ve driven next to this truck before gettin on the 215 from the 60, in so cal, in riverside heard a nasty Jake break, had to look, green under glow lights and seen that industrial spiked visor on the windshield, was going to work early in the morning around 5 am

Funny Steve, "purring motor..." CAT stands for Caterpillar, not Cat ;-)

Awesome truck! You make great Videos. Keep them coming.

Piece of art
