Thanks for all the suggestions. Our trip went great. First night was spent on the road in a rest area near Fredricksburg, VA as we got a late start that day and were trying to cover enough ground to make a meet up with another couple the following day who were coning from another state and accompanying us with their 5th wheel rig. Second night we spent in a campground near Sturbridge, MA and it was adequate for a place to stop for a night. Third night in Old Orchard Beach Campground, ME a top notch facility with all sorts of amenities, and of course priced as such, but very nice.
4th-7th nights at Shore Hills Campground in Boothbay, ME, again another very nice facility with all amenities reasonably priced, quiet and close to what that area has to offer. Then on to Calais, ME for 3 nights at Keenes Lake Campground which was ok, but no sewer hookups and very small spots, however the price made up for any shortcomings. After that we travelled down to Shelburne, NH and spent 2 nights at White Birches Campground. Hard getting in there with a big rig, but once you got on your site it was ok. Left there to head back home and spent a night in Carlisle, PA at Western Village which was probably the nicest place we stayed on the entire trip. Overall the trip went just fine, got to get out of our sweltering southern heat for 2 weeks and enjoyed the cooler weather, relaxing, sight seeing, whale watching, riding motorcycles, eating fattening foods and lots of lobsters. It was my 5th trip to Maine, but only the second time we've camped and the last time was 10 or more years ago. I had a couple of very minor issues with my 15 year old American Eagle, but fortunately I have enough shade tree mechanical ability and general working knowledge to correct them on the road and move on.
