My firestones want a min of 5lbs.I never had any sway problems with my airbags, but I had them plumbed separately and I also always used a huge weight distribution hitch (that wouldn't help in the case of a slide-in camper). I just kept one of those portable 12V air compressors in my truck and I never had a problem. Mine never leaked down over time either. The downside to airbags is you are supposed to keep some air in them at all times (can't remember if I kept 5 or 15 lbs in mine when unloaded), and if you have any air in them when unloaded it will make your ride a bit stiffer.
I plumbed mine separately as well (no on-board air) and would like to tee them together with a valve so I could fill both at the same time then close the valve to keep the air from chasing side-to-side.
