Do any of you haul a kayak on top of a rooftop tent mounted on an off-road trailer? I'm interested in getting a kayak, but am not sure how to mount it. The rooftop tent will be mounted to load bars, but then how should I mount the kayak? I was thinking of something that fit in the rear receiver on the trailer to hold the back end of the kayak, but I plan to have bikes mounted there. An ideas, or better yet, photos?
