Air Bags, also referred to as Air Springs, are located on the RV chassis behind the tires. Depending on the RV make and model, four to eight air bags may be installed. The air bag is constructed of natural rubber, polyester fabric and metallic components. Air Bags should occasionally be washed to remove dirt and debris. A pressure washer is an effective implement to use when washing. It is not necessary to apply lubricated dressings or a wax to the Air Bag for appearance sake, but if you choose to do so use a substance designed to protect the rubber material.

Monaco Coach incorporates a style of rolling lobe bag. The air spring is designed to produce the best overall ride at specified ride height. Raising the ride height provides a longer amount of compression. When the ride height is raised, the ride is actually softer. Lowering the ride height will produce a stiffer ride.

Air Bags are similar to a tire without tread - a containment of air designed to function with pressure and dynamics. The Air Bags utilized by Monaco contain enough stroke in the piston to raise or lower the ride height one inch without damaging the system while providing a uniform ride. There is no need to readjust the ride height. If the Air Bags deflate more on one side of the vehicle when parked, the suspension system will automatically level once the vehicle is started.

When parking the RV for more than thirty days it is recommended to leave the vehicle on suspension with Air Bags inflated. Full ride height and full air pressure. If you choose to release air out of the bags and store them in the down position, a plastic bumper installed inside the bag is designed to protect the air bag from damage. While parked for long periods of time in full sun, as is generally found in Florida, Palm Springs and Arizona, cover the wheel wells to protect air bags from direct sunlight.

Leaning to one side can indicate a malfunctioning Air Bag or a leak in the airline connections. The recommended procedure is to reduce driving speed to 30 mph and find the nearest repair facility. Certain recent model motor homes utilize bags and mounts designed specifically for that product and so it may be necessary to contact the factory direct for replacement parts. In the event air pressure is lost to the system do not crawl under the RV in an attempt to perform repairs. It is extremely dangerous to get under and between the suspension and related components.

Before working on the chassis, block the frame using jack stands as a precaution against rapid air system deflation.
