You might also want to talk to your insurance agent. Don't tell them your plan to go to the track, but get a estimate to increase the liability value, property damage, and medical insurance. Change it just before the race, change it back to normal just afterwords, and you will have the full coverage while at the track.
Should your RV cause the neighbor's to catch fire, and burn the whole place down, you will have slightly more protection. And it might be very expensive to bump into another RV. The extra coverage might be $200 a year, but you will only buy it for a week or less, so perhaps $20? or even $10?
Have fun!
