My camper weighs 4000 and when I add the Reese tow beast and trailer I have another 800. My Dually runs level with 80 lbs and I notice no sway. When not towing I run at 60 to 70 lbs

I don't have overload springs on my truck and don't have as much TC as many.
I run about 45 psi on the driver side and 50-55 psi on the passenger side. Why? It helps compensate for road crown. Loaded truck is just a bit lower in the rear than stock height.

Premium shocks are needed with bags to control the ride.

So I run my air bags at no more than 20 psi.

At 20 psi, your airbags are carrying 1,000 lbs.

OK how much at 0 psi which is what they generally are when I get around to checking them. D--n leaky things.

I love my airbags, this is my fourth truck and I swear by the Firestone bags. I just installed them on my new truck yesterday. As for pressures, when towing my trailer(this is from my 05 F350, I have not yet carried my camper or towed trailer, just installed air bags yesterday), I would use about 35-45psi, depending on load in truck, with camper I would use 55psi fully loaded. I would often adjust with camper when I went off road. I will see if new truck is the same.

Having the in cab controller makes finding the "Sweet spot" alot easier. I run different pressures in my bags almost every time we go out. Depending on what we are carrying in the back. Usually only about + or - about 10 lbs.

Fix the leaks (usually installer error) and check back when they function as designed.

I did and then your second post clicked you might be having loading problems due to leaking bag(s).
Now I read it as you don't like the overload springs loading & unloading?
Is that what you are finding?

The in cab load controller is a great option. I use different pressures depending on load and road/wind conditions but generally just level the camper both front to rear and side to side. On our last outing I was really loaded up, probably as heavy as I'd ever been. My brother and I were on a project trip and had all sorts of tools and equipment - air compressor, ladders, jacks, work benches... I set the pressure at 90, which is the highest I've ever used.

On the way home my brother did experience an air bag failure on the left side - first time that has happened. Yes, it was installer error (I'm the installer) I had run the lines outboard from the bags and then aft to the rear bumper. The air line was rubbing and vibrating across the seam of the bed and it cut a groove into it. His biggest problem was that the auto protect function that keeps the bags at 5 psi minimum kept kicking the compressor on for the last 20 miles home. He didn't know anything about the system or how to disable it.

It was an easy fix though.
