i woulnt, remember your using a belt to drive it, and thats a lot of strain. i understand it would probably pull straight just fine, but i would be concerned when the tires scrub in a turn. although i may be completely wrong.
OR, you could put a ball on the front of your truck and make it easier.Hmm, well the cost of testing it out isn't very high, I may consider giving it a shot. It's really no incline, I literally just want to pull the trailer about 30', there's a tree in the way that makes the truck a pain.
I may also just get the tree cut down, and not fool with it.
Thanks for the information!
