We stayed there last August...
It was a nice place.. our site was not "paved", it had crushed stone..
As to the satellite, I would suspect that depends on which site you have... I believe there might be sites in the back of the campground with limited tree's.. I don't think you'll have any issues with your 40ft RV... We have a 36ft and had plenty of room to maneuver around the campground
If you're bring kids.. They'll like the pool in the back with the slide.. mine did.. However, we spent such little time at the campground, I couldn't give you a full review of the facility... We were too busy sightseeing everything else in the Gettysburg area..
It's a great area to visit.. enjoy !!!
