We are full time in our RV and the fresh water tank was being used in place of the supply hose which froze up. I was not aware the fresh water tank was not receiving enough heat since it is forward of the last heated bay from the steps to the generator.
Anyway, what is done is done and nothing can happen to repair/replace it until it gets warmer. Once it warms up, I can hook up the hose again and try to look at the damage.
My thanks to schlep1967 for the info on replacement tanks. I have started an insurance report and will await their help with the solution.
Just another hiccup. Arnold
