It will open up a whole new world of boondocking. AZ is loaded with wonderful places you can camp for free. Nice NF campgrounds that typically have no utilities of any type. Thousands of square miles of desert areas just waiting for you.
Solar is the best improvement we've ever made to our Class C. In 2013, we spent a grand total of three nights in a commercial campground.
If you're ready to get away from the KOA routine, you'll love your solar.
On the other hand, if you are really attached to your campground pedestal, you've just wasted a few grand.
Enjoy
