Follow-Up:
In a quite cold place, you will have to put piping antigel in your water lines. What I do: I empty every thanks including the hot water thank by opening valves under bed (see manuel for location) After that I install my Rialta abouth 4 inches higher in the back, put 4 gallons of prestone in the water thank and then run every cold water fassets include the toilet and exterior shower, after I do the same with the hot water fassets. Finaly I put windshield washer in every drains include the inside shower + run the shower pump to be sure that there is prestone in the that pump. Then be sure to have no water in your holding thank but you can use winshield washer in toilet and in lavabo drains. And bring water contenant for drinking and cooking. Have fun with it.
