We have been winter Rv camping in our Highland Ridge Open Range Lite (thermal cold weather package) since Nov 2021- Present. We are on a one year camping trip. We purchased the camper in MT and pulled out of the RV dealership parking lot and have been camping ever since. We so far camped in northern Montana near Glacier NP and now in Zion and Bryce Canyon NP areas in Utah. The temperatures were below -0 to -15 for weeks at a time in Montana to include 5 degrees in UT. The camper has preformed well and we live comfortably (wife, me, son, and dog) in the camper. Of course you have to prep and there is some work to winter camping. That means owing a insulated electric heat water hose, heat tape wrapped around the ground water faucet with insulation over it and a wrapped tarp at the bottomto boot. Heat tape wrapped on your septic hose with wrapped insulation and then cold weather tape. Owning multiple cold weater extension cords, and heat lamps. A most is putting a light bulb placed near coils on refridgerator at the outside compartment. Our fridge stopped working because it was below 0. We put the bulb in there and it worked agaim. Placing multiple heat lamps and a space heater underneath your camper for underbelly. A 2nd space heater for inside the camper to compensate the propane heater. A must for below 0 camping is insulating the skirting with either cords of firewood or rv skirting with "foam board" on the backside to shield from freeze or high winds. Its work but it helps! I had a sheet of wood for a entry door to crawl underneath to able to release black and gray tanks. I had two heat lamps pointed at the release valves and the space heater on high at the front to blow towards the back under belly. I had three more heat lamps positioned underneath were i thought the black/ gray tanks were located. We owned four 30 gallon propane tanks. We average one tank every four to six days. Thats why its important to have a electric space heater (good one) to compensate the propane inside the camper. We used reflextics on all the windows for insulation during below zero weeks. The propane heater and stove performed awesome and all the other items in the trailer. We maintained a inside temp at 66 to 73 degrees. Both sinks, toliet, and shower, for the water never froze. We never lost water and remained on city water -connected. We never used the fresh water tank. We kept it empty. I would empty the black and gray when it reached 2/3. We dripped the water at the kitchen sink at night and kept the sink cabinet door open with the space heater pointed towards it to prevent freezing. Other than that "good times!" Lol I give the open range high marks for extreme cold weather camping and liviibility!! Sounds like alot of work but if you like camping and having almost 0 crowds at NP's "its the best!" Show less
