Thank you all for the great advice. I know the winter here will be a cold one, especially compared to winters in Arizona. I think that with some kind of foam insulation board around the bottom of the RV will help keep in some warmth, especially keep the floor from getting too cold and cooling off the inside of the RV.
We do have some fellow RVer's in town that I've also been questioning about winter living, as they will be doing the same here this winter. So far I'm gathering that propane will be an asset. We have a little grill tank and also a large 100 gallon stand up tank. I'll make sure to keep them filled. The little grill tank will be a back up incase we run out in the middle of the night (keep us going till morning when the shops open).Kevin filled them up every couple of days! Days with highs below freezing and lows in the single digits. Ugh. There is a reason we go south for the winter.
Ah yes! We will figure that in as well. Right now it looks like we're going to buckle down here, if it gets too bad we'll probably go into the main house in the basement. I've been reading other winterize threads here and have gathered some useful information on this. Things such as removing ALL water from the pipes etc. Very helpful, thank you!By winterize I meant learning how to dump the water and drain the plumbing so the lines do not freeze up in case your plan fails and you decide to get out
