po, yes, always try to keep the Polycount low. Especially don't use Tris where they are not really required. It's a basic Law :) If you use lots of Tris, then please for something like round shapes of a Porsche or something :)
The reason is: the less Tris you Truck uses, the more Trucks can be in the Game. Trucks and other things, of course.
Have a look at Lithunwrap, Key posted a link in "other tools". Then try to draw the Ladder onto the Texture aso.
Hint: in Lithunwrap> Select all, UV-Map:Box-Mode, then horizonticly Flip the left side of the Truck and lay it over the right side... Feel free to ask when something isn't clear with Lithunrap (happens sometimes :) )
