Air bag question and suspension in general I guess

Looking more into the spring route.

Hellwig has a 2500 and a 3500 overload spring pack. They recommended the 3500 version since the camper plus projected weight gets us close to 3000 lbs. Not sure if that is the right way to look at it, but I have no reason to doubt their recommendation.

Those, plus a sway bar seems to be a pretty good setup ata cost effective price.

Benefit to adding the Torklift stable load too?
