RV Winter use HELP

[NewRVerOH]

Hello, hoping someone can help. I am going to have to start storing my RV (Class A Fleetwood Southwind) in an unheated storage unit. My issue is we use it in the winter for tailgating football games. Previously it was stored in a heated facility so it was never an issue. My question is I need to have water etc kept warm inside the new non heated unit. Should I simply run the furnace in the RV? Is that sufficient for keeping everything warm enough? Should I put a heater in the RV for while it is sitting in storage instead. I do not want any pipes to freeze, etc but winterizing is not an option as I use it for tailgating. Any help would be greatly appreciated.

Hi,

Winterizing is an option so long as you are prepared to redo it. My record was 7 times in one winter.

Using propane to heat may not work unless an extra tank is hooked up.

Are the water tank and waste tanks in enclosed heated compartments?
