My opinion is between the two, Airlift/Firestone, all but the same kits. But as Kayteg1 said, I would stay with what I know and for me that's Airlift because thats what Ive been using for the last 17 Years and has worked. If your local shop that would do the work feels one is better than the other I'd go with that.
Not sure about the 7500# bags and if needed verses the 5000#- as they are not singularly carrying the load, only to assist your spring when/if needed. But haven't researched so don't know pros/cons, may be worth the extra cost.
cartmancartman- no, shocks have zero affect on sag.
So...$2200...No idea what current 'prep' costs. Air bags on hold till determined if needed, thats good. The only other items are wiring to connect camper and tiedowns. Is it known what tiedowns are included in the quote, Happijacks or Torklift? and the method to connect/wire camper, dedicated bed plug?
