All trucks except the International LT have their fuel tanks integrated into the chassis. (have this in mind with configuring the truck as the UI differ)
Accessories, engines, gear boxes doesn't affect mass as far as the trucks I've tested.
However some of the cabins does affect mass.
The mass on Western Star Long 8x6 SFA is the same as SBA even though the SFA is longer.
Propulsion on tires doesn't affect mass but extra set of wheels do.

This will include all trucks and chassis later.
I started with checking the mass for each truck but since the trucks and configs weren't consistent I gave up because of time consumed.
It will also have a more descriptive branding image.

The heaviest trailer is the transformator sitting on the 3 segmented lowboy


* It could be confused with Imperial(UK) measures.
** Calculated from US lb since the game only say in metric tonnes e.g. 12t (11764,83 kg) and isn't accurate enough.
*** Calculated from US gal since switching between game settings would've taken too long.

Thanks for the feedback!
I'm not sure that the mass of the trailer is calculated into the mass of the cargo listed in the job descriptions.
I guess asking on the forums The Pitts would share his in depth knowledge of the game mechanics.

I'm not able to try this myself as I removed the game after the 1.50.x update since the patch made the game unplayable for me because of stuttering and performance losses.

As for the fuel weight, I was required to pull into a weigh station on the trip and weighed it at 175,008 lbs, so the weight definitely goes down with fuel consumption. They probably just don't computer the changing weight during driving because this isn't KSP.

Somehow, I weighed in at 175,107 lb. without refueling after picking up the cargo from the Denver airport and taking it to the closest scales. I used the International with Skyrise sleeper. The achievement popped without delay. The truck weighed 22,349 by itself after refueling so the trailer with the transformer must have weighed about 152,758 (could be off due to my fuel consumption). That's 29,258 lbs. more than what it is reported under the job descriptions.

I am really stumped here. The Fandom page reports the Transformer weighing in at 123,500 lbs. Does this include the trailer it sits on? If so, then how do you get a truck to weigh the required 51,500 lbs. required to add up to 175,000 for the achievement?

@Zekk Distor Thanks for the feedback! Good that you shared your trouble as well, that is very strange :O :greasysideup:

Thanks for the guide!
Just in case anyone is having issues, I was driving the Peterbilt 579 with a Transformator and had my units set to KGs and tonnes, did not get it. Set it to lbs and long tons, did not get it. Set it to only use lbs, and boom, got it.
