One of the things haven't seen mentioned here yet, on my prowler (see Below) you can adjust the pin height--the big box that comes down from the trailer with pin on end is adjustable--haven't looked at alot of other trailer and hardly ever hear it mentioned on posts so may just be on some models (or option?). My first truck was 2500 CTD--traded for present truck and had no problem moving pin up about 6" or so... ... R, J. B.
