i am planning to pull a flatbed car hauler most of the time, usually with cars but i will probably be picking up supplies for my dads business. i live on the top of a hill so it has to be able to go up the hill with a load. th e truck doesn't have a bed on it now i was planing on putting a fifth wheel on it to pull a camper trailer. i will probably exceed the 16000 GVWR. also how am i supposed to ask grigg what the 4-53 and trans cost.
