I've carried up to $1800 worth of camera gear mountain biking, backpacking and wilderness canoing many times. The gear is pretty rugged. You can wrap it with neoprene foam to mitigate shock. I've fallen hard enough a few times in Moab to give my GPS a concussion: It lost all the stored data, including my stored track. Had a map + compass as back-up. The camera and two lenses did fine every time

At the present I carry a much cheaper ($500?) Canon G6 digital. Much smaller and lighter and easier to pad if one finds it necessary. It's in the wilderness areas where I get my best pictures, so I don't want to skimp on the gear I need.
