Staying In Cold Temps

[JandC]

Last year we stayed in central Illinois until late December and experienced some early brutal temperatures. Our 2008 Montana handled 20-30 degree temps very well except for the black tank gate valve freezing up.

As a full timer I learned real quick that by just putting about 1/2 gallon of RV antifreeze down the toilet after emptying the black tank kept the gate valve from freezing no matter how low the temps got. I plan on doing the same thing this year with our new unit. I think it is cheap insurance to keep the valve from freezing.
