Packing for the RV trip out West

What would you bring with you if you were headed on a 12 day RV trip?

The 4 of us have been packing and preparing for 4 days.  Of course we have some books of amazing things to see and do.  All our gear is packed in bins or bags waiting by the front door to be loaded into the 33 ft RV.  We rented the 2011 Sunseeker from Minnesota RV Rental.  This link shows the what the inside of our new home looks like.

We'll try to post daily if we are able to.
