i just borrowed a van from phantom-ontrac for roseville, he had a tailhook rack on the truck, sweet rack . the beauty of this rack was it swung away flat i used it for a repair stand, changed some tires and gearing with the back door of the van open. i carried four race bikes no problem. also there is a strap for the front wheel.
the rack is supplied thru vsi products the web site is www.tailhookracks.com
