Yuma is the best place on earth in the winter in the Western US.
It's a small city with all the necessary amenities. Most RV parks are gravel but we found a gem with no gravel........yes it has grass, concrete and pavement, so no daily dust.
Its rare in AZ to have a reasonable California type park. Its a mile west of downtown ........Wintergardens at 2700 W 8th St.
