SRW 3500 Dodge work with a Arctic Fox 811

I have a 2020 Ram diesel 3500 Crew Cab SRW, but it's a longbed. I carry a 2019 Northstar 12STC, which is a 12' no slide camper. It looks comparable in weight to your 811. The truck does not sit level when loaded and it's surprising how far the truck has to squat before the overload spring is engaged. I added Torklift stable loads, as I want the overload leaf to be engaged when the truck is level. It still squats enough to bother me (and my headlights with oncoming drivers), so I put airbags on the truck, and 25-30 psi brings it level.
