Hitch-mounted motorcycle rack

Thanks Valkyriebush, what you've done is what I've been thinking about doing. However, I have to use a tow dolly on my rig which may not allow enough ground clearance. Another thing I was planning was to simply weld in frame brackets and use some steel C channels bolted to the frame brackets for a semi-permanent motorcycle carrier on my Caravan. That way I could mount the carrier higher up to allow for the extra ground clearance I'd need with the tow dolly. It's just that those hitch mounted carriers are so much more convenient!(heavy sigh)
