Empty bed vs empty camper….not the same. Just a little mis-interpretation.
egarant, yes I’d maybe endeavor to get the upper overloads engage a little more, presuming you like how the lowers have leveled it back up. However the more you engage the uppers, the less you’ll engage the lowers.
That said it’s fine tuning at this point. And a sway bar may make the most difference. However if it doesn’t have unacceptable body roll while driving, I wouldn’t be chasing minutia like pulling out of parking lots, personally.
Without incurring expense, just fake in some temporary upper “stable loads”. Clamp a hockey puck or hardwood block or whatever in there and see what you think first.
