Rear end spring capacities under your camper & towing?

What does your manual show the max loads are for your truck? I can't amagen you don't already have enough spring, the only thing is the truck must drop a couple inches for the top springs to start working.
But upper stable loads (torklift) will fix that.

Definitely check out Stableloads. $100 - $400 depending on which version you opt to purchase. Airbags would be the last option. Airbags can unload the suspension. The Airbags may try to carry the load instead of the suspension.
