RVng in that time frame can be tricky (especially your return) Part of RVng is looking at long range wx forecasts. I will say, Jan-Mar in AZ and the states you will return thru, can be tricky, and road conditions can be dangerous
I have lived in the SW for years now and I love AZ. But it can have long and very cold stretches of WX from Jan even thru late Mar, with snow at times and high winds
Be flexible and be prepared Some folks dont like walking to the shower house when its cold. Be aware, just hooking up to shore on the way wont winterize your RV.
I winterized my rig about 2 weeks ago. I saw the temps would be down to 29 degrees for a night coming up for the first time this winter
So I winterized, and sho enough, a night later, it got to 27. I left the grey water drain valve open (by mistake), and there was a tad trickle of water that had frozen right there at the cap. It got to 50 that day: It dosent take long to freeze
Practice now on how to winterize your RV Dont do it on the road the first time if you can help it. See what it takes to do it, choose the method you want, have all the items you need to do it on the road. Stress can be high on winter RV trips, no need to make it worse
I prefer the air compressor tech. Yes, I bought a $150 pancake compressor and wired it in my RV storage compartment, not just for that, but also for other possible needs And yes, I use small amount if antifreeze for the pump. Thats just me
You mentioned winterizing and then staying in hotels on the way back. Not a bad idea, it will just be weather dependant
As said, you will likely experience stretches of below 30 weather in Az during your travel times Take look at typical Jan wx in the Flagstaff area Average low is 17
