My kayaks are about the same length as a canoe, and I would probably haul my canoe on it too. I thought about a lumber rack, but I would rather fabricate something semi-permanent. That way I don't have to have a place to store it when I'm not using it and don't have to mess with taking it on and off... I may fabricate something that can serve as a roll bar and add a piece that will stick over the cab to it... I'm going to go pick up square steel tubing in the morning and go from there with it. I still haven't come up with a good design, so I'm open to suggestion...
