Got a 5th wheel camper to pull behind my 2500 HD Denali with Duramax

Trailer according to the title is 11,800 lbs

Did not tow well on the first outing after picking it up . the truck jerked like riding a horse and serious lack of power like the converter or rear axle gear not allowing the motor to work as it should , truck did not squat that bad so I'm  not sure what the problem is . Camper is definitely heavy but was not expecting it to be that bad .   Air bags help ??

The jerking sounds like 5th wheel ker-chunk. What brand 5th wheel hitch and what brand of pin box on the trailer. A lot of people like the MOR-Ryde pin box or the Trailair. Some have gone to the Andersen hitch that uses an A frame in the bed and converts the king pin to a ball mount to eliminate the ker-chunk. The Andersen A frame connects to a B&W Turnover Ball gooseneck  hitch and that allows you to remove everything and have a flat floor in the bed of the truck when you are not towing the trailer.


Can't help with the power problem if you are punching the Tow/Haul button. That diesel ought to pull it.

When you say it jerks do you mean like 5th wheel kerchunk from the normal play/slop in the 5th wheel hitch or do you mean the bucking from the infamous interstate crack bounce that sets in like a resonant frequency? If it is the bounce I would make sure my trailer nose weight is not too heavy and you might try a Trailair pin box.
