I am the owner of a 2012 Winnebago Tour on a Freightliner chassis. A 4 in 1 gauge on the dash, part number W22-00013-022, developed a crack in the housing, resulting in a considerable air leak. My service center advised me the part is unavailable, anywhere, at any price. I called the FCCC support line and was told the part is no longer manufactured. Alternate part numbers are likewise no longer manufactured. The FCCC advisor told me their is no known solution to this issue. I am certain the coach wouldn't pass a DOT inspection and would be placed out of service if it were a commercial vehicle. I understand this is not an uncommon problem. I would think this is a safety issue based on the fact that the sudden loss of air pleasure could result in diminished braking.
