We recently stayed for a long weekend at the Outlanders campground after we received a referral from a friend and could not have been more happy with our stay.  The RV sites at this campground are very spaced out, you have a lot of room to each side of your RV.  The park and facilities were very clean.  They have a playground for the kids, fishing ponds, cabins, pet friendly with a dog park and they are located right along the Shenandoah river.  You can go tubing on the river but need to provide your own tubes.  The ride down the river from one end of the park to the other is around 30 minutes.  Also for all of the people attached to the internet like us we were able to have plenty of cell signal to hotspot and get internet.
