Hi all, Haven't posted in a couple years - mostly problem free with my 298BHS (2009), but now I have a question about the grey and black water tanks. The 298BHS has a toilet and sink for my boys in the back bunk, and a full bath up front for my wife and I. We love it! My problem is that I am not sure if I am draining the rear bath black and grey water correctly. I know the front drain is okay, as there are two valves/handles, and two gauges on the check panel. The rear tanks
also show two separate tanks (grey and black) on the guage panel, but this last trip, it shows the rear black tank as 2/3 full after dumping it - problem is, there is only one valve in the back of the trailer to dump (separate dump connection from the front tanks). I assumed all along that grey water from the sink in back just dumped into the black water tank - thus one valve. But why is the rear black guage showing 2/3 full, while the rear grey empty?!
Hasn't been a problem until now, so I guess it's not really a problem then? Just wondering if anyone knew if my trailer actually has separate grey and black water tanks in the rear? I know the front has two. Sorry to make so complicated, just trying to explain what I observed. Thanks for any help!
