Where about in AZ are you?
Regardless, reading about it on the web and actually doing it are two different beasts. First year is the hardest, it'll get easier and better with each season.
The real danger is reading stuff coming from people that aren't in a RV. Their perception will be much different on just about everything. A 40 degree morning in a single wide with an AZ/FL/TX room is a lot different then in an open air bottom RV with just an awning. The list will continue from not having wind breaks to supporting buildings to storage to enough AC.
What snowbird RV'ers do have in their favor is the freedom to move around and see the country at will. So when some are sweating in 90 degree heat because it's too soon to head north, you can be part of the 70 degree club enjoying the middle of the country experiencing new things.
