A Guide to Camping Level, Travel Height, and Storage
The suspension system is an essential component of your caravan, providing stability and support while on the road. Understanding the operation of the stage 3 airbags and how to adjust them correctly can ensure that you have a safe and comfortable journey.
Suspension System and Operation of Stage 3 Airbags (Base Models)
The stage 3 airbags in your caravan provide the necessary support for your suspension system. Here are some tips to help you operate your stage 3 airbags correctly:
Camping Level
Your airbag system requires adjustment to find the right level when camping and traveling. You can start by lowering the airbags until the van is on bump stops. Then raise or lower the nose of the van to have it close to level front to back. You can then raise whichever side of the caravan is low using the up control on the Cruisemaster panel. Once you're happy with the level, shut the compressor off and put your stabilizer legs down.
Note: If the compressor has been off for some time, it will need a few minutes to fill the air tank before you can pump the airbags up.
Travel Height
The critical function for the correct traveling arrangement is the HEIGHT of the caravan, NOT the airbag pressure. This is measured from the top of the bump stop to the bottom of the chassis rails.
Cruisemaster XT Air has three different travel heights depending on the axle load capacity. This information is located on the Cruisemaster identification plate fixed to the drawbar.
Note: Your airbag pressure will likely be different from side to side when setting this up, and that is normal.
Operating PSI Range
The normal operating PSI range is 45-60 for tandem axle and up to 80 max for single axle. Anything more than this can show overloading in your caravan or incorrect travel height. Traveling with the airbags higher or lower than these PSI settings can result in damage to your ZONE RV and may not be covered under warranty.
Storage
If storing your caravan for long periods, the suspension should be set at normal “Travel” height to protect the bump stops and airbags from compression damage.
Operating in the “Get You Home” Mode (Emergencies Only): In the event of air loss, it is possible to run the caravan on the bump stops. The “Get You Home” feature of the suspension has been successfully used on normal roads. Extreme care and very slow speeds are required if running with airbags deflated. Off-road conditions, especially, can cause damage to airbags and drawbar mounting brackets. It may be advisable in these circumstances to lower tire pressures to provide additional cushioning to road bumps.
Note: Warranty does not apply under these conditions.
The suspension system in your caravan is an essential component that requires regular maintenance and proper operation to ensure a safe and comfortable journey. By following the tips outlined in this article for camping level, travel height, and storage, you can prolong the life of your stage 3 airbags and protect your ZONE RV. Remember, if you have any concerns about the operation or maintenance of your suspension system, it is always best to seek the advice of a qualified professional.
