Any Point On Heating

I have recently moved and now reside near Roseburg Oregon. Don't know what to expect as far as winters go yet, so far it's been pretty cold. I know that this recent cold snap is a 40 year fluke.. Who would have thought that Eugene would get -10..... One year in Astoria I did heat the trailer during a cold snap and I think it did create more condensation than If I had just left it alone. Hopefully by this time next year I will have my RV garage built...
