Heavy American Truck Mod Needed

[Dakoetaw1976]

I am still looking,after 7 hrs of searching for an American Truck mod for heavy transports. Preferably with the "Long 8x4 or Long 12x4 chasis." I was customizing a Peterbilt 352 but it's got no sound and it makes game run slow or crash. I can't use a long-nose rig because turning radius is too large and the damn thing gets stuck on exit,entrance ramps, If someone could point me in the right way I'd be grateful.
