Should I have to winterize my camper even though I have never used it and I plan on taking it out in January. For contacts I live in central Virginia and I am heading to Texas. When I get to Texas I will be living in it for 2 years.
The only way to avoid the risk of bursting pipes and damaged appliances in freezing weather is to winterize. You can avoid winterization IF you are USING the trailer in below freezing temps, but its risky, you MUST keep the furnace and hot water heater on 24/7, just like your house. This will cost a small fortune in propane (and electricity if you put the water heater in electric only mode) and you need to monitor underbelly/basement temps.
I winterize my trailer when I don't use it from November to early February, even though I use it in late February, March and early April on ski trips. It's not until we arrive at the RV park near the ski area that I flush out the RV antifreeze. Once there is water in the water heater and pipes, the furnace and water heater stay on in freezing weather, even when we are traveling. This uses a ton of propane, but it keeps the critical systems (the water heater in my trailer) from freezing. Even with the heat on, you risk freezing depending on how poorly insulated the trailer and how cold it gets. You could add skirting and a space heater underneath, but if you aren't using the trailer, it's a LOT cheaper and less risky to just winterize.
