Great semi! Found a couple of glitches though. As you can see in the pic, extra light on the ground at the back, headlights don't actually project (high beams on in this pic) and the tag axle works perfectly, except when driving, it doesn't roll. lol
do you have a headlight mod in, from the in-game mod hub or from anywhere else? Also try just putting the truck in a profile with only that truck mod in the profile
