just a side note / the flip side of things ...
we have SuperSprings on most all of the work trucks here
2005 Dodge Ram 2500 -- "supersprings" (300,000 miles on truck).
2000 Chevy 2500 -- "supersprings" (260,000 miles on truck).
1999 Dodge Ram 2500 -- "supersprings" (180,000 miles on truck).
2001 Toyota Tundra -- "hellwig helper springs" (130,000 miles on truck).
My truck is a 2000 Ford F-150 -- "supersprings"
The over-load springs or helper springs are nice if you don't want to add air or have to worry about air lines potentially leaking. But with the over-load springs or helper springs your truck will ride a bit rough when the camper is not on the truck, and there is not much adjustability in the springs.
The air bags should give you a smoother ride when the camper is off the truck, and you have more control on ride and how much air you put in them. Only disadvantage ... they need a little maintenance from time to time (no big deal though).
I'm not a suspension expert, but here is a quick over view ...
maybe go with over-load springs or helper springs for easy, reliability, no maintenance.
maybe go with air bags for the more flexibility & versatility & smoother ride when empty
The air bags REALLY lift the truck fast & easy if you are carrying alot of weight in a 1/2 ton truck.
