if you do that be sure to place a 60 or 100-watt incandescent light bulb in the wet bay. many RVs, even basement models, don't heat that area. cheap insurance. Amazon still has incandescent bulbs available.
I ended up purchasing & using a couple of low wattage "personal heaters", which put out about 200W. I prefer these to the light bulbs as those filaments can be fragile, especially in a 100W incandescent bulb. One of those heaters with an inline thermostat electric cord do a good job of keep everything above freezing. Most days, if the day forecast is mid-30's or higher, I unplug them until evening sets in.
But when I DO winterize, I use air to blow out each line, individually. Just make sure to keep each faucet open until all of the water is out. Make sure to blow out the toilet, sprayer, washer/dryer hookup (if equipped), outdoor shower and the black tank rinse (if equipped).
Putting RV antifreeze in the drains is a good protection, as well.
Right before you leave for your trip, fill your freshwater tank and head south! Enjoy the trip!
