If you are looking to be in the heart of Pennsylvania Dutch country, Old Mill Stream at Lancaster and Roamer's Retreat in Kinzers, both on US 30 are fine CG's.
I'm a little partial to OMS. It has a unique layout, in that you park parrallel to the roadway. Most of it is under shade trees so Sat. TV may be a problem but there is CATV. Adjacent to the CG is Dutch Wonderland amusment park - within walking distance.
Farther east from Lancaster, closer to Paradise and Intercourse, (and I'll not mention Blue Ball
) is Roamer's Retreat. Open and shaded camping and in the midst of true Amish farmland.
You can spend a week in Lancaster County and only begin to cover the sights there.
