I want to beef up my rear suspension so that my truck doesn't sag with my travel trailer on. I am thinking about air bags or timbrens. The problem is that I also want to be able to unhitch and go wheeling. Trailer weighs 3800# wet. Do I need a different set of leaf springs and the air bags, or just one or the other? I have an Icon stage 4 suspension and they recommended to take out the overload spring and put in the AAL that comes with their kit.
I have read through this forum 'till my eyes crossed and can't seem to get a handle on just the right setup.
