I have a new to me F5 that I'd like to use when out on a motorcycle and I'm concerned about durability issues. I'm thinking of getting a Pelican case of the right size and bolting it to the bikes luggage rack. I'd use fitted foam on the inside to carry the camera a lens or two and a SB-28 flash. I'm concerned about vibration, not just engine vibs but also all the bumping and banging from riding off road. The bike is a KTM 950 Adventure which is a large dual sport, for on and off road, and much, most really of my riding with the camera will be off road. Anybody have any experience beating on an F5 in this manner? I know its supposed to be tough but just how tough?
