It looks like a Polar Vortex is getting its act together and should affect folks as far south as South Florida. Most of us should see temperatures in the forties, if not lower. Sometime ago I advised my dear readers to get out the heaters and check them out. If you didn't do that, DO IT NOW! I also recommended that you run your on board propane gas; we call it our big ass, heater. However; we also recommend that gate guards use the free electricity we enjoy due to the high consumption of most propane heaters. Unfortunately, most RV's are not wired for that kind of amp draw, so gate guards should get creative in that regard. If you are fortunate enough to have both a 30 and 50 amp plug on your support trailer or generator you can buy an adaptor from Amazon to plug extension cords into. Then run a heavy duty extension cord through the slideout seal for the heater(s).
RV's are generally not built or suited for extended periods of cold weather. We suffered through a winter once (with some days at or below zero) in our Class A and will never do it again. If you have slideouts, they are notorious for leaking. Sometimes it as simple as ensuring that they are fully extended. For some reason it seems easier to note the leakage in cooler weather. I can feel it seeping in, particularly on one slideout. Everyone's situation will vary, but strips of foam placed in the opening may help. Finally, get your "long handles" and other winter apparel out, or bought. If you're like me you'll resist getting out of shorts and clogs for as long as possible. The other morning I had a hoodie and shorts on. Unfortunately, the cold will win out so prepare now.
