Lifted trucks and 5th wheels do not go together. Not saying you can't do it, but you will hate yourself.

My old neighbor had a lifted F250 with air bags in the rear that towed awesome

my 95 f350 i sold was only an inch lower than this one, so my trailer setups work fine with this new truck, the trailers i have i can adjust the hitch height, i dont pull any 5th wheel hitch trailers i got all goose necks that adjust. i hooked up the stock trailer today and loaded 5 horses in and took it about 25 miles and pulled nice
