I have a 2004 Monaco Windsor with a Cummins 400hp. Am currently traveling and discovered large amount of exhaust fumes coming through the access panel in the bedroom. After investigating appears the exhaust pipe flange that attaches to the engine blower has broken due to a loose exhaust pipe support clamp. I have applied a temporary fix, but need to find a repair shop in the Houston area that can provide the fix. Any suggestions would be appreciated.
