Hello, was wondering if anyone knew much about these trucks or has had experience with them. We are going to be pulling a 44' trailer (kinda a race type rig) and thought it would serve the purpose well. We currently have a FL-60 pulling the 48' trailer and it work's great, but didn't need that much of a truck for this trailer. We are looking at a 4 door duramax with allison auto. Any thoughts?
