We stayed here our last few trips to Daytona
http://www.daytonarvpark.com/
we stayed a week after the Turkey Rod Run the last 2 years, plus a couple of brief stops while passing through. It is a nice new park maybe 3 years old with large sites and plenty of room to get a big rig maneuvered in. They are trying to cater to a high end customer with the big rig rv's, but are truck conversion friendly, particularly during race week, bike week, and the rod run, they ease up the standards a bit as to race trailers and such vs. a traditional rv. They hesitate a bit at our converted race trailer in the "regular" season, but we tell them it is a fifth wheel toy hauler (technically true) and we have not had a problem. Full hookup sites are $39.50, but I know they get a bit more during special event like everybody else in town. Free offsite trailer parking (limited) for car/mc haulers. No tents, rv's only.
Close to the track, about 5-10 minutes away with traffic, just south of Beville on Nova, and maybe 10-15 minutes from Main Street area.
