Hi, For those of you with air bags on the rear axle and a fifth wheel, how much pressure do you use? I started with 30 PSI and now increased to 38 PSI. About 2,750# of pin weight. Crespro
No two trucks and trailers are the same. You have to adjust the air pressure to what is right for your rig. Generally you want to run the pressure up to the point that you are just lifted off the overload springs and the ride is comfortable.
Remember that you have a 3/4 ton truck and they are limited on cargo carrying or payload capacity. The air springs do not increase the trucks capacity to carry a load.
