Different points of view are what makes this forum interesting. Always something new or different. The method that works for us is: start early and end early. Keep the daily mileage between 200 and 225 miles. If we unexpectedly find something interesting, or just get the urge to stop, do it, we might never pass this way again. We reserve our camp sites 4 days out. Small state parks if available, however we usually end up in private parks, more expensive yes but knowing we have a spot when the days drive is done seems to free us up. Gas...I fill it when it hits half a tank and try to stick to name brands. We utilize RVparkreviews.com constantly.
