Air Pressure for airlift airbags
I installed a set of airlift airbags on my 03 2500 HD Silverado. Wondering what a good air pressure is to run on them with a 8500 lb Cougar 5th wheel. I put #45 unloaded but seems like it needs more.

I have a 2008 3500 with Airlift bags, towing a fiver with around 3,000 lbs of pin weight. After playing around with it for awhile, I've found that inflating to 45 lbs unhitched is the sweet spot for us. As others have said, there is no one correct answer as everyone's setup is different. I'd start out at 40 or 50 lbs, and increase/decrease as needed, keeping in mind that the goal is to level out the rig and improve ride comfort. Also pay attention to the amount of squat when you hitch up. Should be a two or three inches, but not much more. When running unloaded, I keep 5 lbs in the bags to maintain their shape as directed in the owner's manual.
What is your air bag psi after load is applied?
