How is your Dodge lifted?
If it's all spring lift on the rear, you will be fighting the sway problem.
The best way to haul a camper with a lifted truck is to use the stock springs & lift it by other means. Shackle flips, blocks, or drop brackets with stock springs will keep your camper from swaying.
I'm running 42" tires on my crew with 8" of lift. I used shackle flips & blocks with stock 4800 lb springs & have practically no sway with the camper. I also run the airbags where about 60% of the weight is off the springs, I find it lets them work better.
Lift springs will eventually sag under constant loading giving a nice, sloppy ride...
(wore out a set in a couple seasons)
I find the biggest prob with a lifted camper hauler is the height thing. Came back once with a birds nest stuck in the fridge vent....have to keep an eye out for power lines, low flying planes.....
