This is a pic of my multi day set up. The Gobi's swallow up tons of gear including my fairly big Coleman fuel stove (which I carry because it's been toted on bikes in my family since 1970) MSR bottle, extra tubes, all kinds of stuff. The big 90L drybag holds tent, sleeping bag, pillow, and a huge 3" thick self inflating sleeping pad that is like staying at the hotel.
The dry bag is only about 9" across and weighs about 22 lbs for the entire "motel". And it's slightly narrower than the panniers.
Not that a pic of a 950 with Gobi's was needed, just loved that bike.
