If you have the time before you leave consider installing an accumulator, a small plastic ball with a diaphragm air on one side and water on the other. This will allow the pump to cycle on and depending on the air head you have set will allow you to do short draws of water before the pump cycles again. Even with this I would turn the pump off when you know you will not be drawing water for a while, ie leaving the trailer.
Watch that hill up to Ricks Glen. I had to drive 50 miles out and around to Williamsport to keep from coming back down it. Great campground just a hell of a hill.
