very new 2 rving, bought a 2006 dutchman denali model 31RGBS-M5. Looking at the drain valves, the one infront of the axles in labeled sewer outlet connection, it has the main valve, but also has 2 lil push pull handles connected 2 this,, the one behind the axle is labed waste water holding tank, My question is which is black, which is gray tank??? any thoughts, very new to this, thanks
Not sure how differant the 2006 would be from my 2009 but I believe you have one and a half baths in your denali like I did, and the half bath is located forward of the axles, then the valve in front of axles is black water for the half bath. The full bath black water comes from behind the axles and this should be where you see the two differant valves at the drain, the grey water for all sinks baths will be the smaller (2"?) that comes from left as you look at valves, and black water from full bath will be the larger pipe that goes straight toward the centerline of camper.
Even if yours isn't exactly the same, the grey water will be smaller diameter than black water...
