You're going to be disappointed with that Big Block rear. I put a fresh one on for the 2011 EOAR and it was gone before the end of the trip (the front was OK though).
All my camping gear is of the backpacking variety. Very light and packs down small. I also pack a "LuxuryLite" cot in with the sleeping bag. It takes little room and my back thanks me every night I don't sleep on the ground.
Coordinate with your riding partners to minimize duplicate items (i.e. tools, tubes, pump, cook stove, etc).
I always pack a pair of Klim GoreTex socks in case my boots get soaked (which seems to happen every trip)
