For those of you with defined SUA -
How well does it handle a load? I'm looking at about 400 pounds of roof top tent, camping gear, water, and gas. Would be on the truck for days to weeks at a time. That's on top of the bed cage and full size spare.
How much sag have you had in the leaf pack over time and what kind of load are you routinely carrying?
Any other comments you have on the kit? Unless some folks give me some clear warnings, I'm going to go ahead and order one soon.
