Another camper top question

If I add a camper top (something like a Leer 100R or similar) would I need to upgrade the suspension on my truck? I've got the stock Prerunner suspension, with some TRD Bilstein shocks and I don't want it to sag in the back. Would putting a Add-A-Leaf in the back help out or would it not be necessary? The most I'll probably be hauling around in the back is my hunting/camping gear and some SCUBA gear.

 

I wouldn't think that weight would make for much of a sag if any at all. If I were you i'd wait and see for sure, might be able to save a few bucks and some time. Mine doesn't sag with my shell, tool box, high lift and floor jack, Compressor. Thats in there on a daily basis.
