So I've been looking at adding air bags to the rear of my truck since I tow and haul somewhat regularly and I'm always bottoming out the rear due to the Deaver springs. I also have bent the frame a little from some harsh hits while off roading with camping gear in the back . I was planning on straightening the frame with a comealong, welding in a crossmember, and adding air bags and air bumps. But I'm thinking that rather than add the Ø2.00" x 2.5" air bumps, I can use the Ø2.00 x 4" air bumps and not use air bags. The travel on the air bumps would work as an airbag. When just derbing around I'd have my normal suspension with air bumps (I add less pressure in the air bumps). When I load up the back, I've got air bags (I add more pressure). Seems like a great way to have the best of both worlds, and I don't see any issue in doing this.
What do you all think? I see RPG did basically the same thing on the Raptor and it looks like it works pretty well.

Otherwise I was going to fab up some mounts with the Firestone 9000 bags since they won't limit my travel. Pretty much like what this guy did on his Taco:
