I currently use a Rotovac CFX which I have not been satisfied with. My water source is the customer's tap which feeds directly to my RV 360 so I am at the mercy of the customer's water pressure of quality of their hot water heater. Buying a new portable with a built in heater like a Mytee isn't an option as I would just view that as a waste of money when I already have a working portable. So I could buy a rotovac docking station which gives me a 27 gallon holding tank and put two bucket heaters in there to heat the water up. Maybe an in-line heater? I am thinking my only real option besides a docking station for another $995 is saving up for an entry TM and cargo van.
