Full timing in any RV in cold climates could be miserable unless the RV was equipped for it as well as possible. There are heating pads for holding tanks, and DIY measures to keep as much warmth inside as possible. Blocking off the front cab/windshield and side windows helps. Furnaces use a lot of propane and battery power. You need ventilation while staying warm. If you do not have truck mechanic, propane/electric appliance, HVAC, and DIY skills for maintaining the 12volt battery and 120 volt AC systems and time, workspace and help necessary to make an old RV livable, I'd recommend saving your money and if you buy an RV, make it some 6 years old and plan on having tires, AC unit, furnace, fridge, etc. replaced/repaired when and if needed. Tires on RV's become unsafe sitting parked for 4 or more years even though they may look new. Check the DOT codes on the tires to determine age. Unsafe tires can cause loss of control and steel belts can flail the underside of the RV wiping out tanks, propane lines and wiring. Talk to a number of others who have lived in RV's fulltime in cold and hot weather. I would recommend a 27 foot class C with rear bedroom and good storage and cabinet space like our Tioga model 26Q, discontinued a few years ago but available used.
