'09 LTZ Questions about a lift

[bobsburban]

I’ve been having trouble with my Tahoe sagging like crazy whenever I hook my small dump trailer up to it. Makes it look squatted. I’m running 5100’s and the 81069s in the rear. Will bags fix that issue? Do they make stiffer springs than the z71 springs?

Look at these Dobinson springs (https://baselineoverland.com/produc...2007-on-with-660-880-lb-constant-load-c09-037) on that same website. They appear to be somewhat stiffer. Think I'm going to add a pair plus some new air bags after towing the trailer this past week. The truck sat fairly level even with the extra hitch weight (the Winnebago is up to 600 lbs now, plus the WDH weight) but I'd like a bit more cushion given the need for portable solar, 20 extra gallons of water, and a small generator in the truck.
