One of the features on the Pleasure-Way Plateau (and Sprinter vans in general) is what are called "Ride Rite" air springs.? They are installed on the rear axel between the chassis frame and the leaf springs. An optional air suspension compressor kit allows you to adjust the pressure in the air springs from within the vehicle.? I know that these springs are normally used to compensate for varying load conditions.? ?For example, when towing a boat or snowmobile trailer, one can pump air into the springs to level the vehicle if it is sagging under the tongue's weight.? Are there other benefits to having this feature?? Can one use it to level the vehicle at the camp site?? How is the ride affected by the air pressure setting?
