Driving me nuts trying to find out where the exhaust fumes are coming in at - had it to two local RV dealers and both took money but no results .Starts coming inside after driving 45 minutes or so - helps if you shut rear bedroom door so i'm sure its coming in back there .2006 Winnebago Journey with Cat 350 hp engine .........heeeeelllllppppp .

Thoughts ......ideas .......anything

Maybe if I left 5 gallons of gas in the bedroom the problem would disappear .With the luck I'm having this year nothing would happen .........
