You might want to look into what the Parker area has to offer. RV parks on both sides of the Colorado River,AZ & CA. some small and reasonable.
We're on the river, in a park with 200+ sites but because it's spread out we hardly notice the size. We don't get as much wind as some other areas of the desert south west because of the river valley. Down side is it's an old park with limited facilities and decent shopping is 14 miles south; Parker; or 27 miles north in Lake Havasu City.
2 1/2 > 3 hrs from Pheonix, Vegas, Yuma and Palm Springs.
