Can someone explain to me which vent is what on my 2007 Classic Ltd FB? I am having issues with sewer smell in the coach following traveling and have ruled out (I think) dry P valves as a cause. The front of the trailer is to the right.
The center black vent in the photo is the fan with the push button on it located in the bathroom ceiling. It seems to be able to be popped up or down. How do I know what position to put it in? When I began running this bathroom fan, the smell does seem to evacuate the coach pretty quickly.
How about the other two white vents on either side of the black one-- is one of these from the black tank and another from the grey? Anyone have experience with those 360 degree 'tails' to help vent the black tank? Trying to get to the bottom stinky stink stink I've been having...
