Thanks for catching that @JAMANG! Much appreciated! The 4 was in there from before I added the A.S.S. Guess I just forgot to change it.
Sometimes THAT guy is the only guy who spots the thing that might otherwise kill 50 people. I never know why no-one wants to be him - he's a switched on dude!

Hate to be THAT guy, but the build uses 6 pistons, not 4. 4 on the bottom and 1 on each side for the A.S.S.

@Mattheus... Yep! There's also a brand new Hydrogen engine version and separate dedicated Hydrogen tanker version.

updated...

Certainly not! She's getting on a bit now (4 years old nearly!) and there's nothing worse than a sour old T.A.R.T!

That's great! We wouldn't want her to be sour *ba-dum tsh*

UPDATE V1.3
===========
By request, the T.A.R.T now features a brand new A.S.S self-righting system. See description & change notes for details.

All new screenshots on their way...

Good catch Leo - I would've forgotten if you hadn't mentioned it! She's all serviced & happy now!

@Leo... yes. Can't say for other countries but here in England, tart is a very old slang term that originally meant a prostitute. Today it's mostly used as a well-natured taunt or jibe between friends, though it can also be a mild insult. These days it can refer to men, women, animals - anything that gives itself freely.
A cat for example that will sit on anyones lap can be called a tart.
We also have the pastry kind. The bittersweet flavour would be "tarte" with an e, taken from the old-English "teart" meaning "sharp" or "rough". The Americanised version drops the e.

I think "tart" I think of a pastry or the flavor. Does it have another meaning that I don't know about? (Maybe similar to a certain type of pie?)

P.O.P.T.A.R.T. confirmed

@Captain Redbeard...
A most excellent beard colour sir!
I'm glad you're getting as much pleasure from your T.A.R.T's as I do from mine. They're usually the first thing I build too & you're right, there's just nothing quite like the sight of a fresh one charging up for her first trip out. I can never manage to wait the last few minutes for her to charge fully - it's like she's begging to be used!
The mark of a good T.A.R.T that is!

I can't get enough of this T.A.R.T., honestly whenever I'm starting out fresh I have to bang one out. There's nothing as satisfying as seeing one of these T.A.R.T.s patiently waiting for the next hard ride. The aesthetics, the bones, the surprisingly large capacity to be filled up, just the best. Though there are many like it, I cherish each T.A.R.T. the same.

10/10 T.A.R.T.

@CanisDirus... I see you like the simple pleasures too! Thanks very much! I'm following you now also... I think that means we go in a circle! Like at 2m:11s... https://www.youtube.com/watch?v=k5FRbZ1zZm4
Hehe!

This is awesome work i love the build !!! Its a beauty
I follow !

@Smokki... Thankyou! One of the biggest kicks I get out of doing workshop stuff is when someone takes inspiration from it... or better yet they remember it! That to me is like gold dust!
If only I still had the world I used for the screenshots... might have to build that again sometime.

So great to see this back :) This vehicle (and the way you showcased it in the screenshots) was always very inspirationale for me.

@⎛⎝๖ۣۜÐÆ ๖ۣۜTigar⎠⎞...
Yep, that's the same truck then. No-one ever made one identical. Similar yes but not identical.
Nice to hear that someone remembers my work fondly, so thanks! - and thanks for the welcome back!
There will be more... a lot more...

it might have been as it looks identical to the one in 1 of my old saves if so welcome back and hope to see more

@Garbage Scow Captain... It's ok - if anyone asks you can say it's educational material and you're learning about how little trucks are made.

@Man of culture... Glad I could help! Yes, T.A.R.T's all come pre-fitted with CushTec's Mk1 "Ample"(TM) cushions as standard. For the more discerning cushion connoisseur however, we recommend upgrading to the Mk3 "Comely"(TM) models with added piles protection & adjustable lumbar support. This upgrade is free within the warranty period.

@cptsavarus Hey, thanks man. Really helped. I assume your delightful T.A.R.T offers its own cushions, do I have to pay a little extra?

That last pic might Not be Safe For Work ;)

@⎛⎝๖ۣۜÐÆ ๖ۣۜTigar⎠⎞...
There are a lot of trucks on the workshop with a similar design - this one was one of the first. I uploaded it a long time ago & it got nearly 13,000 views, so it could be this is the same truck you're remembering... but then my Steam account was wiped & I lost all my blueprints, including this one... so I re-built it from old screenshots.
Glad you like anyway. More like this on the way...

this one looks so much like a other older one of similar design i miss that one so yay to its newer cousin time to test this one out

@Man of culture...
Perhaps adjust your seating position. A good cushion may also help

I'm... So uncomfortable...

Thanks very much! Glad you like!

amazing
