For those folks who haven't winterized their MH yet because they might want to travel before it gets seriously cold, do you partially winterize to protect against a surprise dip in temperatures (if not stored inside)? And if you do a partial winterization, what is it that you actually do? Thanks in advance for guidance on partial winterizations.
1. Drain the fresh water tank and holding tanks, top off fuel tank and propane tank.
2. Place 2 small thermostatically controlled 110 volt heaters, one in each end of the wet bay, set to come on at about 40 degrees F.
3. Place a small thermostatically controlled 110 volt heater in the "living room" interior area, set to come on at <60 degrees F.
4. Turn on coach bedroom (propane) heater, set to maintain the lowest setting on the thermostat (approximately 55 degrees F.)
5. Leave the coach plugged in to 50 amp, so both sets of batteries remain fully charged.
6. That's it! Worked fine the last 2 winters, with coach sitting outside in the driveway, and temps occasionally dipping into the teens.
You are sort of all in or not. Once the water system is protected it will only take an hour or so flush everything out, flush some sanitizer through the fresh water tank, drain that and add water and be good to go. Once you have done the winterizing process onece or twice it doesn't take long to do either. A few hours of your time and $20 of RV antifreeze is much better than repairing a frozen pump, burst lines, a damaged water heater or Aqua Hot, a burst manifold, damaged faucets or valves or any of the many other problems that could happen.
We winterize and leave MN when it has been -30°, really. We take a couple gallons of bottled water. Two days to warm and we are ready to go.
