Good luck on your adventure! Never forget the awesome restorative power of a well-timed PB&J sandwich and clear the trash out of the front seat floor area each time you stop--it'll make you feel lighter, honest :) We did a several thousand mile, 2 month trip around the great national parks of the west last fall and those two tips above are part of the wisdom we distilled out of all those hours spent in a fully packed SUV together ;) PS We're still married!
