It is extremely frustrating, so much in fact my husband and I decided to go in 50/50 with my parents and buy some land in a community camp ground. It’s a dry spot, but there is a community clubhouse a short drive away. It’s not the same as traveling around and exploring different places, but atleast we we have a place to go if we don’t want to fight the reservation system. Thousand trails or another private camping network is an option too. I wasn’t super impressed with some of the thousand trails facilities, but some are really nice and you can almost always get a spot somewhere.
