We are traveling to Pennsylvania in a Class A 40' diesel with Jeep towable to visit the grand kids in late April. We are trying to find a park/campground to stay at for 6 weeks. We are interested in a quadrant area between Hagerstown MD, Chambersburg PA, Harrisburg PA, and Gettysburg PA. I've researched Good Sam, KOA, RV Park Reviews, All Stays, etc for our choices. It seems the Eastern US likes shorter stays at any specific location. We just started full-timing in Sept 2013. We haven't boondocked yet except for a Walmart parking lot once. A paved site would be great but not necessary. But 50 amp service and water ARE necessary, and having a sewer hookup would be a PLUS! All this 'convenience' stated, we are ok with State or Federal campgrounds if they are by suggestion. Does anyone have suggestions for nice parks in the stated area?
