My RV winterization technique is to spend the winter at the Howls. Warm winter (avg January temp is 66F. Of course, the hot summer temps encourage us to travel to more temperate climates when the desert summer is six weeks off (May Day) and head for cooler climes in the intermountain west. Lots of great trout fishing to try. I've never been close to being a winter person. Don't like snow and ice. As close to winter as I ever want to get is watching the Winter Olympics on the toob.
I've read some of the posts in this thread and y'all must have the real pioneer spirit, but those who enjoy winter should do that. But not me. Winter is a time to be endured, not enjoyed. I DO enjoy the winter temps of SW Arizona and Punta Penasco is a two-hour drive in the toad. There is a beachfront RV park where we'd probably go.
