I read these posts and I look at where the all the posters live. Man, you folks deal with a lot of issues that are just unknown to those of us in the southern quarter of the US. I winterized last week. This morning it was 31 and this afternoon will see 60s. We will have a few days (at least traditionally we would) where temps don't get above freezing but that is a very small percentage of the year. Still, I have to winterize and exercise my generator monthly for me to feel OK about the situation. And occasionally the temps get stuck in the teen or twenties for a few days.
I have an indoor, non climate controlled RV storage place about three miles from my home so I just go out there the first week or so of every month on a pretty day, back it out, fire up the generator, turn on the AC which has 1500 watt heat strips and go up the road about twenty miles to a good hambooger joint, leave the genset running under load, have a burger, drive back and put it into storage for another month. I like to drive the whole rig once a month and our weather always allows that to happen.
ALSO, I top out the gas tank after each of these journeys (which takes about 4+ gallons of gas for the 40 mile trip) to help prevent condensation from the air space in the tank.
Again, I would really have pause in how to handle the off season if I lived north very far up the continent.
