No flags are needed for trails in Moab. The past two years only the trail leader, shotgunner, and tailgunners ran flags on the trail but only to identify them as such (dunes are another story). If you do a search on here you will find many check lists of items to carry. ZuZoo is just like any other trip on the trail, carry the basic nessesities. And its a good idea to tie down EVERYTHINGthat can fly and hit you in the head or get lodged under a gas or break pedal! I tie everything down that moves including occupents (buckle up).
