Hi Malcom and Randy,
We wintered in Mesa, AZ last year at the Apache Wells RV Resort, and liked it well enough to return to the same site this winter.
It's an over 55 park and full of Canadians, so'll you'll have lots of neighbors who speak your language.
One must reserve by April or May of 2013 to have a site next winter.
Sue and I like it because it is immaculately maintained and one of the smaller CalAm RV resorts. It is located on the north city limits of Mesa with splendid views and easy access to hiking trails in the Tonto National Forest.
The RV Resort itself has a heated pool that allows us to swim every day,
Main drawback is that like most RV resorts in the Phoenix area, the sites are close together.
