2013 Thunderbolt XLR 380 AMP (Grey & Black water Tanks)
I took delivery of the 5th wheel without any explanation or walkthrough of the unit,,,,my bad, but lets not go there!
I have level indication inside the unit for black water, grey water 1, and grey water 2. Outside the RV on the drivers side inside the service compartment there is one black water and one grey water manual dump T handles.
But now here is why I ask this question. The 380 AMP has a 1/2 bath in the garage. Behind the wheels there is another T handle, which I thought must have been for the washer connection drain, or the second grey water tank...NOT.
After some warranty work, while setting up at the RV Resort, I found the valve between the wheels had been left closed. (This valve is almost exactly below the 1/2 bath) The RV was used for a 2 day outing prior to finding this. After hooking up the sewer hose I opened the closed valve in the back, and to my surprise it was NOT grey water at all!
Can some one with a 380 AMP tell me if your unit is the same way. And what liqiods go into each grey water tank?
