If you tow with a Ram 1500, please tell me how the truck is configured, and what you are towing. Please only reply if you are doing this or have done it personally.
Tows my tiny 20ft 3500 lb kz tt beautifully. No problem for lack of power, easily passing much bigger trucks towing much larger trailers up steep grades.
Only negative, the coil springs sag as I reach max payload. Sumo spring helpers worked wonders.
I use a plain ball hitch and occasionally a friction bar for anti sway.
