Truck and camper in sig below. Running Toyo MTs. 3970lb load capacity aired up. Airbags take 70+ lbs to level truck back up. CG is slightly behind the rear axle but there's a Cummins up front and a hi @ss mega cab to ballast it!
A dually would be more stable but it drives fine even with the wrong application type shocks on it.
Camper is def over 4000lbs based on weights seen on here.
Maiden voyage was from Seattle to Anchorage right during spring breakup, read massive frost heaves for hundreds of miles on end, pulling a 16' tandem trailer on a short hitch extension.
No issues with a 7 yr old 100k mile plus truck hauling and pulling that kind of weight so I figure "normal" service really isn't taxing the truck that bad.
My only reccomendations are to have good stiff shocks for low speed damping, adequate tires and find a way to engage the overload leafs. I haven't since the Dodge requires drilling the leaf to install stable loads on a 2500. Shocks and stable loads would get rid of most of the body roll my truck has. That said there haven't been any oh shat! moments even coming into a turn a little hot. Only place I feel the roll is creeping thru successive potholes in 1st gear.
Oh the exhaust brake don hurt either!
