We have an AirSafe hitch that we love, but the last trip the airbags were not holding air making it a rough trip on the rig (and boy can we feel the difference). Thought maybe one of the bags had sprung a leak as spraying soap on the connections was yielding no results...bad news was that the bags are not cheap to replace 🙁. Spent yesterday trying to isolate which bag was leaking and low and behold - the air valve had the leak. It only showed up when you moved it around, but there is was!! $3.75 part and we’re ready to go again!! Happy day!
