Waste Tanks and Hook Ups
When staying at a campsite with full hook ups, do you leave the tank valves open all the time or do you let them fill up and then drain?
I could see letting the black tank fill in order to get a good chance of emptying the solids....
Also is it possible to open the grey tanks to allow them to flow onto the black tank?
I have a 2002 Sprinter.....thanks Bill
