I started with 50 lbs in the air bags but pumped them up to about 70 to stiffen the rear to counteract body roll. I don’t really think there was any difference in the camper unit porposing between the 2 different air bag settings but I can only try it at 50 lbs again and see. I will be adding a Helwig sway bar for the body roll later on.
Thanks

When I had my Lance 918 (which was a tank), I ran my bags at 40 pounds maximum and I ran Rancho RS 9000 shocks in the front and rear with a factory sway bars front and rear.. I've since switched campers and shocks I have a lighter camper now (Palomino SS1500) which weighs about 2500 wet. I run 30 in the rear bags maximum. I went to SkyJacker Monotube Black Max shocks. You never want to run a pressurized nitrogen shock on a truck, always a conventional hydraulic dampened shock, preferrably with strong rebound damping.
Porposing is caused by a couple things, The Cg can be too far back which can be corrected by loading the unit with your heavier gear farther forward (so long as the camper is loaded as far forward as possible, that is, not having a unit for an 8 foot box loaded in a 6.5 foot box (that puts the Cg back and causes handling issues, Too much air in the bags causing the weight to transfer to the front axle abruptly on throttle changes or a swoopy road and having too much air in the bags causing the truck to sit un-level.
You only want enough air in the bags to level the truck and no more.
Even when I pull my tri axle gooseneck overloaded with round hay bales, I never run over 60 psi in the bags, only enough to level the truck and no more.
One, I think you have too much air in your bags.
Two, your front shocks (and possible rear shocks) need changed to a conventional hydraulic mono tube shock, Rancho, SkyJacker or whatever you prefer but no gas charged shocks. Only conventional
Three. Your Cg May be too far back and if it is, load the front of the camper with heavier stuff and keep your black and grey tanks as close to empty as possible.
I think a shock replacement and lowering your pressure will do the trick.
