Black Water/Grey Water and Galley holding tanks
Hi there. We can't find the answer to this anywhere. Have a brand new to us 2015 Sierra 393CK destination trailer. The specs we had said there should be a black water holding tank, a grey water holding tank and a galley holding tank. We seem to be missing a tank, and the black and grey water tanks are plumbed together, so we need to dump the tank daily. Is this normal?
