Wes, that's impressive!
I just know I had an onboard in cab pressure gage that I could air up and down each bag. At 5psi unloaded when the RV was added the pressure went to 30psi.
No math formula need for me just visual proof.
That is why I always ask people if the air pressure they are referring to is loaded of unloaded. Still I don't understand why tires are not affected in the same way.

Sitting on the overloads in a static state is not the problem, however, with the dynamics of varying road conditions, and without some help (bag, supersprings, etc) I frequently bottom out.
I fill to ~50-60 PSI. Why I have blow 2 bags is a mystery to me. Both times have been on long trips, some of it over some bad roads.
50-60 before hitching up ???
After, and that's what it takes to level out the truck to my calibrated eye.
If I recall, they are rated to 80 psi

:h So is that a fact on your truck?
Not so on mine, there is a very noticeable increase in pressure when the load/fifth wheel is dropped down on the hitch.

No disrespect you are completely wrong! I had bags on my 11 RAM. I ran them at 5psi unloaded. Once the 4-5K pin weight was added the pressure in the bags went to 30psi.

Define very heavy. Either you somehow got 2 defective airbags, not likely cause if they work once they are pretty much good, or you have a stupid heavy pin weight if the dually needs airbags maxed out plus some!
Or are they getting cut by something? You're not specific about what happened.

Airbags are there to LEVEL the truck, not return it to empty ride height when loaded. Ideally the truck should ride level when loaded on the overload springs.
Dry pin weight is 3225lbs on the 2014 RW415. Even if loading it added 2000lbs to the pin weight you should be well within the payload capacity of a 2013 DRW Chevy.
X-whatever on these two points:
1. That's what the overloads are there for.
2. How much pressure are you putting in the bags?
