[Starchmill]

I last used my rig during Thanksgiving and it has been sitting closed up in the yard since. I still needed to dump the black tank though (I had added several gallons of antifreeze to insure it wouldn't freeze in there). So I went to empty the tank and found the valve frozen shut. The other valves were frozen also, even though those tanks were empty. I decided to turn on the heat in the unit for a few hours to see if it would thaw anything and much to my surprize, after about 2-3 hours all the valves were thawed and functioning again. I guess I was very surprized that there was enough heat going into the underbelly that it loosened things up that quickly. Just thought I'd post this as an FYI for anyone else that has cause to fool with those valves in the dead of winter. Marcia
