I had a problem with my parking brake valve leaking air in the park position. I first called the roadmaster tech support and was told that it was covered under the roadmaster's 3 year chassis warranty. When, I had the valve replaced it was not covered and I had to pay over $300.00. The reason roadmaster gave, is that the valve was mounted in the coach and not on the chassis. Even though the parking brake valve is part of the chassis componet. Does anybody know for a fact that the valve is covered or not under the roadmaster 3 year warranty? By the way my coach is a 2006 Diplomat, which was bought July 2005.

it is not covered.

Hey iceit -

Any update? Have you talked to RoadMaster directly about the valve?

Keep us posted,
Ron
