I measured my stock lift, when I had everything out of my bed, when it was Rhino-lined. I cut a dowel rod to that height, and have it in the back of my truck. Whatever I hook onto, I air my air bags up to stock height. That way, I am not blinding anyone, playing airport, or have my headlights stuck into the ground 50 ft. in front of my truck. I am at stock height, no matter what I am pulling.
I have put 100 psi. in my bags before. But, normally, its around 80-90 psi. with what I normally pull. With the tool boxes in the back. Not hauling anything, I am running 15 psi.
