Exterior back mounts for kayaks?

Looks like the weight is held by the hitch so the mounting to the rear wall would not have to be really strong. There should be room between tail lights for two kayaks. If not, you can easily purchase a set of clip on tail lights that could plug in to the hitch wiring.

Thanks for posting - my wife would love a kayak for her birthday. I'm skeptical, remembering a sore back the time I rode a kayak and I'm much older now.
