I wouldn't... when we did something similar in Wyoming, it ended up costing a pretty penny in little issues. Things like my Crossfire tire system, which hadn't lost a pound of air previously, started leaking, I burned up a water pump because it was left on and we hadn't thought to cut off water to the icemaker line (which was exposed to the outside in the connection to the fridge itself).. it's a long list. Probably the biggest items was that I started having issues with my hydraulic pump after that, and my inverter became intermittent (turned out to be a cracked circiut board).
Again, many of my issues could just be coincidence, but overall, the year after doing that winter stint was the most expensive in general maintenance by a factor of 4 in the years since I had the coach.
