mesa rv parks
If you traveling thre Mesa Arizona, there are many RV parks that serve the "snowbirds" that come to visit in the winter time. They are beginning to head north about now so there are plenty of spots available.
Hard to select one because they are all decent. Are you planning to stay and visit, or only a one night stop over. Are you coming via route 10 Though Tucson, Route 40 through Flagstaff or another route.
Will try to help, but again there are plenty of satisfactory sites that would work. A Woodalls campground guide would give better suggestions along with prices and ratings.
Welcome to the desert, remember, it's getting warm here now.
