The furnaces are propane?
You have an auto gen start?
leave the thermostat on 50. Batteries will drive the fans in furnaces a long time. When they get low the auto gen start will recharge them.
A lot of people express concern about equipment running while they are no there.
I dunno how to advise on that.
We leave our heating/cooling on when gone from home for periods of time.
Perhaps just make sure every thing is in working order and nothing blocking furnaces and so forth.
Heat from furnaces will heat the bays and tanks enough to keep from freezing
I didn't read all the post so if this covers same territory, excuse.
Check propane tank every week then maybe every two weeks if need be and of course the whole coach.
And make sure the storage facility is ok with it. And if yours gos up and is the cause for others it's your liability. Park away from others. Too much caution, just reacting to so many posts of fear of propane and furnaces etc.
