As some one said, go ahead and try it in the manner you desire to camp - if it works then your okay. We started out with the same concept, but then seen where having a small generator available would be nice, so we bought a Honda 2000i, and it has been worth every dime we spent.....back in '02! We could pull into a Rest Area, turn on the generator and make a pot of coffee, and then be back on the road. It was also great when we boondocked for a week or more...charged those batteries right up. It is a personal call, but you can always change your mind. Safe travels.
