What to do with my leafs

I am on the fence as to what to do with my leafs. I have an 06 d cab 4x4 and the rears hits the bump stops when pulling my trailer with the bikes on it. I want to remedy this but don't want to spend a ton of cash because I plan on a new truck in a few years. O the TSB was never done on this truck. I have installed 5100's and the front is set 2nd clip from the bottom and the truck sits just about level ( I think the back may be a hair lower ) I would like to gain back the rake for trailering. What should I do?

 

Ride rite bags in the rear maybe?
