A compass, paper maps and or big map books, sleeping bags that are the proper size for each person, twice as much water as you think you will ever need, a CB set that plugs into 12 Volt power plug (at night a CB can reach out a distance when cell phones are not within range of any towers), a GPS unit that is NOT part of a cell phone, extra big shade hats, SPF 50 sun-screen lotion, (very important sunglasses and even an extra pair), TP, what ever kind of snack bars the people going along like (Rx bars such as coconut chocolate and Kind bars such as caramel almond & sea salt are good), a propane stove, propane bottles and lighters, caned food, a pot, a can opener, knifes forks spoons plates, salt, peanut butter and bread. I do not know how many people are going along, but if the number of people are more than would be able to sleep in the cab of the truck in sleeping bags, than also bring a tent, mosquito-repellant, a shade tarp with poles ropes and long pegs.
