I have two 110-gallon fresh water tanks in my bus, either side of the fuel tank and just behind the front axle. Each tank hangs by ten 1/2"-threaded hangers, and is sheathed on all four sides and bottom with 1/2" plywood. They each have a 3/4" ball valve at their outlets, and they are inter-connected with a length of 3/4" galvanized pipe that has a drain valve at one end. This means that I can completely drain either tank if needed, or shut off one of the tanks if needed. Each tank has its own gravity-feed inlet that's a stainless-steel marine deck fill, much nicer than the usual plastic RV crap. Either or both tanks can also be filled from the shore water connections by simply opening one valve next to my pumps. The tanks were roto-molded by Ronco Plastics in Tustin CA from 3/8" polyethylene, with spin-welded fittings for their inlets, outlets and vents. In addition, the left tank has a pair of 1/4" fittings for a sight glass to see its water level; it also has a 1/2" fitting in the top for a return line from the bathroom sink's faucet so I'll be able to run the not-yet-hot water back into the tank instead of wasting it while waiting for it to get hot. So far, so good.
