Airbags not working with overloads
I just put on Airlift airbags on my 3500 and am finding that it is preventing the load from being carried on the overloads. I have done a fair amount of googling and am not finding people with my p...

Thanks for all the different perspectives. I stole from several of you to get to where I am. I did various loaded and unloaded measurements and it was eye opening from several perspectives.
1 - With only the suspension loaded with the camper, air bags not present, I was about half an inch off the bumpstops, which is why I was having them hit some on my drive home after purchase.
2 - With the airbags aired down, and siting fully on the bags internal stops, the camper ended up being perfectly level taken on the refrigerator. Although the tire wells were different heights, various factors ended up combining to be where I wanted even though I didn't realize it.
With that information, I am going to play around with upper overload stop extension lengths to try to get the fully loaded suspension to be just above the air bag bump stops to try to be close to level when aired down and then air up the bags to get 1-1.5 inches of travel in the suspension when driving and see how that rides.
This will end up being a long way around to getting to where a large percentage of truckcamper+airbag users end up with the upper stable loads and airbags. Once I have the airbag pressure and overload extensions dialed in, I expect that I should be happy with the ride.
KKeller - thanks for the pictures. I had a similar thought to cut down the lower bracket for the airbags to get it sit closer to the axle (my bags replace the factory bump stop, directly under the frame) and may still do that depending on how my extension experiment goes. I can gain about 3/4 inches from that lower bracket.
