Here is a link to pictures I took of my East Coast Ride. I left Sunday, July 23rd and was back Saturday July 30th. I stayed in my tent most fo the time (second night at a friend's in Bar Harbour Maine, the last night in a motel in Querbec.)
Near the beginning is a picture of my bike ready to go. The dry bag on the back seat has my tent, two sleeping bags, my Airmatress (Exped Synmat 9 Delux which ontains a pump built into it) and a little camp chair. I didn't cook so had no cooking gear. When the tent was wet I strapped it on top of the drybag.

I have side cases if I wanted to use them but have decided I don't really like them on the bike.
I should be doing the same setup for my ride to Grand Canyon which I am starting on the labour day weekend.
