Opinions on air bags for 2015 HD 3500 to carry my Lance 855s

I have to agree with the above post to try your setup and adjust accordingly. Spring weights vary between models and generations of trucks. My main spring pack must be softer because I need my overloads engaged for the camper to be stable even with an OEM anti-sway bar. Once I have that additional spring weight engaged, mine is steady. Sitting only on the main springs and individually plumbed air bags, I get rocking in and out of driveways. Perhaps I could eliminate more sway with a heavier bar or more rear sag, but I prefer the ride with the overload springs engaged and only a slight sag in the rear from level.

I've tried all the combinations with different bag pressure and upper and lower overloads engaged/disengaged in addition to adjusting shock dampening to find my best ride. Some people will find their sweet spot with few changes and some will never find it until they change trucks.
