Winter Fresh Water Use
Our Thor Gemini 23TW we are picking up soon is equipped with heating pads on the waste tanks. We are travelling through the Canadian Rockies for a few days, so will likely encounter freezing temperatures.
I'm aware the fresh water system is not heated. Is it best not to use this at all and just use bottled water for toilet flushing, wash-up, etc?
I have read the other posts on heated tanks, but any additional tips or thoughts are appreciated.
