You will need flags that go to 10ft orange in color.No riding double unless atv came from factory for it.I always lock my stuff 5 gals of race fuel is a small fortune.The state campgrounds are first come first serve But you can reserve in Little Sahara Powersports campground.Both places have elec and water sites and there are some public showers.Try this site and it will answer a lot of your questions.there are also part stores and gas available at the dunes. :biggrin:
