On our SOB TT we had 2 tanks. First one had 2 valves and 2 outlets. 4 years later they still had 2 tanks, but somewhere they tied either the 2 tanks or outlets together. So it ended up as 2 tanks 1 pull 1 drain. I actually had a smile on my face at the dump station.

Now I am stick in the middle (with you), 2 tanks 2 valves 1 outlet. BTW after working in the basement (pass trough storage) I had taken off the back panel to access the plumbing. Got to see how the sausage was made. I would recommend EVERYONE do this before your first time or or shortly there after. Cool stuff back there. Use a good flashlight, see how waterlines are ran, see how your dump valve cables are routed. Coming from TT background to 5er made for a good education doing this. It is real interesting if you have a residential fridge.

Oh and so you know I am still on this thread, you can see how the tanks are situated and which one is where. Including your approximate location of your fresh water tank.
