It's cool mod, especially new engines for T-series (I don't really care about other vehicles :).
Just a little suggestion: can you add some V8 or V12, like Cat 3408 (as V8) and Detroit Diesel 12v71 as V12 (in some versions it could have 900 hp beeing two stroke engine). And not only spec. of engines, but also their models.
Make T-Series great again!
I barely touched the surface of this mod, but ive wanted power steering in this game since it first came out, and I dont know how you did it, or why its taken this long for someone to do, but that alone is 5 stars to me! Please implement this on every car you possibly can if its not too much trouble. Thank you for this VERY WELL MADE mod, and for future updates!
Are you perhaps thinking about adding engines to the hopper? A V8 would be nice, or even a V6 considering the Hooper Unlimited mod was just released on the forums not too long ago... either way great mod, love your work.
