We have completed a 3500 mile trip in ten states and find a shortage of RV people on the roads. At the Flying-J truck fuel pits we could see no lines in RV fuel pits, places to eat are empty, and rest stops only have trucks and cars. One park in PA had one unit in place out of 53 sites, in WV park had 60 plus sites and as we pulled out one unit was in park and they planned to move out in hour or so. In MD state park office gave me a map and told me to find site you like. This park had 200 plus sites and we found six units, tents and all. KY Horse Park has 260 sites, on weekend park was 80% full but on Sunday by noon only around 20 units in park. We found the same thing every place we went and we moved every two to four days. Wal-Mart lots were also empty of RV units day and night. We think the high fuel prices have run most RV people off the road. It added around $300 to $400 to our trip for diesel fuel. I do not think anyone will have a problem with full parks this summer. Have other RV people who travel full time found the same thing?
