Camper shell AAL question

I installed a camper shell on my 08 Pre-runner with the TSB done. The truck sits ass down now and bottoms lightly when fully loaded. I want to add a leaf that both lifts slightly and adds some carrying capacity. Anyone have a suggestion for a reasonble fix? I wanted to go with bags because I do haul heavy loads on ocassion but they are a bit pricey. thanks in advance for your time and opinions.

 

Cheap fix would probably be an AAL from Toytech. Seems weird your butt would sag with the TSB done even with a cap.

 

x2 I'd check and make sure they put the TSB 4 leaf packs on. I think there have been a few cases where the dealers just put a new set of non-TSB 3 leaf pack on the truck.

 

In my case they didn't put anything on the first time. Had to go back and tell what's up, then get the real 4 leaf TSB kit.

 

Thanks guys, I did get the 4 leaf packs after they tried to install a 3 and a 4 leaf pack. It sits about dead level with a 1.5 spacer lift in the front and the TSB in the rear. Once I start to load it drops low in the rear. I may try bags after all. Nothing else seems to work as well IMHO.
