Spare fluids!!

Definitely a tire repair kit and an air compressor. Even if it's a slow/cheap air compressor, it's better than nothing.

Pull out your spare and make sure it's in good shape in case it needs to be run.

Are you expecting to break/damage the rear shocks? I'd do a full suspension travel test to make sure nothing on them binds up and make sure the top bushings are properly installed.

If your UCA's have been touched recently, make sure that the nuts are properly torqued. I've seen a few people this past year had that nut back off, with no spare. It sucked for them to get it back together and home again.
