good answer mindless,
everyone is pretty much self sufficient in all aspects. (grill, food, beverages, tools, spare parts, etc.)
especially with an event such as big dogs which is so far away, and has such a vast network of trails, we all plan & pack for the worst case scenario. When we as a group have attended this event in the past, we run trails that are rated 9+ on a scale of 1-11. they are considered some of the most challenging here on the east coast, and are not for vehicles that aren\'t heavily modified.
the majority of the participants @ bigdogs run trails rated 6 and below. and they provide very experienced trail guides for all group levels. another thing to consider is that we all trailer our rigs which allows us to push the envelope that much further. a wheeler that driven to the trails is not one I would recommend taking above level 6 or 7.
we all either tent camp or have enclosed trailers with sleeping quarters.
