The heavy duty SumoSprings kit you would want for your 2021 Ford F-250 would be the # SSR-128-47-2 which has a 5k capacity. If there is no bump stop perch over the axle you would instead need the kit part # SSR-129-47-2.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…
