When using an air suspension system like part # F2071, the amount of air you keep in the air bags will vary.

It is recommended to keep at least 5 psi in the system but you want to inflate the system so that the motorhome will be level front to rear when looking from the side. The amount of pressure depends on the load it is carrying. As a general rule, the air helper springs will support approximately 40 lbs of load for each psi of inflation pressure (per pair). An example is that a system inflated to 50 psi will support a load of 2,000 lbs.
