Hello, We have a Leisure Travel Free Spirit on a Mercedes dually. Had an issue on the last trip. The outside right rear lost air, also had the problem of not being able to access the valve without removing the wheel cover. Had to reach into the wheel cutout to try and access the 135 degree extender which had loosened causing the air to escape. Fortunately I was able to get my fingers in the rim to tighten it up. I put 2" Wheel Masters extenders on the fronts and rear. I do have the braided extenders for the inside tires. Have not experienced any issues with those.
