We live in Santa Fe, NM at 7,000 ft. and it does get reasonably cold around here. Not like up north, but we see 10 - 20 F many winter nights and it freezes from late October to mid May. Our lowest lows may hit -20 or so. Since the DW still works, I try to avoid that any more, we can't can't just pick up and go a little farther south. But, we do still use the rig in the winter months and I wind up putting the rig in and out of winterization multiple times a year. In Jan & Feb I'll pull liquid soaps and the like out, but other wise everything stays put. The rig is parked at home with 30 Amp power and I have a good charger on it that maintains the batteries in the cold months. No problems. I spend maybe 30 minutes to winterize or de-winterize for these cold season trips. In the spring I give the rig a full maintenance schedule.
