Easy install, set up without an air compressor for automatic fill. Most of time have 5 psi in both bags as per instructions. When towing manually add air to 25 psi as level assist. Tow vehicle is equipment with air suspension so bags aid in not having to run suspension system compressor very much. So far so good............
