i dont think he was confused about the 30' law...he was asking what they consider "trucks", whether it meant any trucks or just commercial trucks? theres a big difference in a semi truck and a ford ranger "truck tractor" refers to semi trucks without the box....his dodge ram isnt considered a truck tractor so he should be fine....basically, a semi with a 28' box or 30' box is ok, but nothing bigger...a semi with a 35' box isnt allowed, but a regular truck with a 35' box should be fine since that particular line in the law didnt mention single or combined gvwr
