Sounds awesome. Good luck wih the cooking!!!
Two tips. When you are cooking somewhere that the food you are going to eat is the only option, use good(kingsford) charcol. I have struggled with heat from our cheap grocery store charcol.
Second tip. If you have a car or ability to bring heavier items, get a galvanized trash can. Take the lid and put upside down on the ground. You can flatten the handle if you want. put your charcol on that, then the D.O. on top of the charcol. Then of course, the charcol on the lid of the D.O. This helps reflect the heat up and isn't lost in the dirt/sand/soil. You could always turn the trashcan upside down and do the same thing using it as a work(cook)bench. Being galvanized, you may want to start a fire in it first to burn off the galvanized coating as it is not healthy for you. If the trash can is not an option, put some aluminum foil on the ground a littl bigger than the DO and again put the charcol on that to help reflect the heat up.
D.O. cooking is fun. Google and there are a bunch of websites. Also you can find books on it with recipes in a lot of stores like Cabela's, Gander Mountain, maybe even the local bookstore.
Don't forget the tongs to pick up and place your charcol pieces under and on top of the D.O.
