Upper-Middle East Coast Campgrounds?

...We would prefer something quiet, but with full hookups so we don't have to "rough it" too much, not a resort full of kids. We won't use a pool or arcade or tennis courts, just looking for nice, clean parks with some good but not too difficult hiking trails and that sort of thing, and dog friendly...Any recommendations?...

In my experience, very few commercial RV parks/campgrounds have enough property to have hiking trails of any length. So, you would need to look at ones close to public lands/recreation areas. Many state and county parks have more land and thus hiking and biking trails, etc. Checkout Delaware State Parks, Maryland State Parks, New Jersey State Parks, Pennsylvania State Parks, and New York State Parks. However, these public parks may not have full hookups. Most have at least some electric sites and often have a dump station. Some have pet restrictions and some limit pets to specific campsites and areas within the parks. Corps of Engineers Lakes often have campgrounds with some electric sites and a dump station.
