Ignore the naysayers, critics and party poopers. Prolonged road trips with an RV or Pick-up camper are fantastic. My suggestion would be that your primary purpose would be to have a fun adventure and the trail angel stuff be secoundary. Explore the Appalacians and all the wonderful things they have to offer. See the sights and meet great people. You will meet lots of folks doing the same. Don't miss all those church and volunteer fire company dinners! Good food at ridiculous low prices. Your main concern at this point should be what kind of rig do you want. Pulling a tag-along RV can be hard on your vehical. Make sure you have a pick-up with plenty of muscle. Them hills can be steep, curvy and long, up and down. If you decide on a self contained unit, the smaller the better. If you make one of your purposes to map your route, write a journal, etc., that would be great and probably helpful to others.
