Here's what I typically bring when I do undeveloped/primitive camping:

* tent
* air mattress (and battery-powered air pump)
* sleeping bag + pillow
* EARPLUGS
* camping chair/per person (walmart has decent inexpensive ones)
* camping table (to use for food prep)
* 5-gallon water container (from walmart), only for longer trips
* 2-gallon garden sprayer for low-volume washing, cleaning, and showering needs.
* PETT portable toilet and toilet paper OR shovel (but do not bury toilet paper)
* propane cooking appliances
* food prep items (foil, plastic wrap, baggies, paper towels, etc), utensils, plates, bowls, cups, spices, etc.
* a few trash bags (and bungee cords or rope to secure the bags to a roof rack to pack it out)
* INSECT REPELLENT!
* propane lantern
* flashlight(s)
* food, beverages, and a cooler to keep it cold (of course)
* fanny pack or backpack (if hiking is planned)

That's a pretty complete list of gear.

As with any camping trip, plan your meals accordingly. It's very easy to unnecessarily overpack. For the campWAMP trip, plan for:

Saturday breakfast (on your own or fast food on the road)
Saturday lunch (some people pick up a Subway sandwich in Truckee, then eat it at the bus drop-off)
Saturday dinner (at camp)

Sunday breakfast (at camp)
Sunday lunch
Sunday dinner (fast food on the road, or at home)
