Air bag pressure question

i experienced the same thing being over inflated. I'd try 50#, then 40.

Sorry to revive this, but got a similar question. Had my 5er about 6 weeks and been running about 60#. Seem to get a lot of bounce and almost bucking feel on the crappier roads. Went up all the way to 90# and no improvement. Almost felt worst on one stretch.
Does anyone think backing it down to 30-40 might be better?

I'm headed out next week on a 7hr trip so I guess I'll have plenty of time to experiment with the on board controller.

I have the Airlift wireless system. 5 years of flawless operation and I love it.

I highly recommend the additional $ for the in-cab controller. My scientific method is pump until it's comfortable which is usually around 50lb. Too much air and it seems to "roll" back and forth too much. Too little and I get to blind people at night.

Interesting..... I've generally run mine at 80-85psi (when loaded) carrying the Lance 1181 on a F350, DRW CC. Got about 65K with her on the truck fully loaded. With a long bed (WB) and all that weight you're going to get some nice ride on the highway, but on unimproved gravel or dirt F.S. rides she's going to roll a bit. Seems to be a nice balance of using the air bags and the leaf's, also doesn't beat the heck out of the camper! Empty, I take the bags down to 10-15psi!
I think part of the goal is handling and ride comfort, but an equal part should be protection of the cargo and cargo transport (truck)!

I adjust so that I have some contact with the overloads with my bumpstop extensions. I'd say it is slightly lower in rear than without load without significant pressure in air bags. The point is to add a little stability by letting the overloads be engaged.

I have tried several settings to find the best ride. I have Airlift 5000 on a 2015 Chevy HD3500. I find that at higher pressures I did not bounce as much as with lower pressures. Since my springs did not squat onto the helpers with my Lance 855s, I got the bags just for a more stable ride - no bouncing. Seems to work best for me at 75 psig so far, but I am still toying with it.

Too much air makes a worse ride. The balance is to have weight on the overload springs, but not too high. Never adjust because of headlite aim or wanting the truck to look like it does empty. I have a 2500 with a Lance 835. It weighs 3000 lbs loaded at the scales. I usually run about 15 lbs and 20 - 25 with a boat or atv trailer in tow. I ran about 55 lbs and was bouncing all over the road. Of course, we all have somewhat different setups, but my point is try different pressures and hopefully you will find where you like it the most.

Do you guys with air bags run just enough pressure in order to keep the rear end the same height it was without the TC or something else?

If I did that the camper would be nose down. F350 empty rides with the back of the bed at least 3" above level. With my airbags at 30psi I run with a level bed and my stable loads lightly engaged on the overload springs

Goal = reduce sag and just enough pressure to make initial contact between bump stops and overload springs. It is a balance.
