How to go with the flow but restricted by reservations?

Use your next FHU site to take the guesswork out of dry camping. Rather than hooking everything up, leave your RV unhooked. Then, using common sense conservation, go about your normal behaviors. If you run out of water/power/etc., you have your hookup right there, so you aren't going to be left high and dry. And you'll then know how long you can last when dry camping without going into extreme conservation efforts.
