The facts are thus: The longer your trailer the less campsites you will fit in. The closer to the camping date you get, the less sites will be available that you will fit into. If you make your reservations 6 months ahead of time you will find a whole lot more sites available to fit you then if you make your reservation 6 days ahead of time. So like a lot of things in life, it's a trade off; you can get one or the other. You can please all of the people some of the time, but you can't please all of the people all of the time.
