Unfortunately, I don’t have any pictures of the rack I use for my tandem that I got last year. I use a
Hollywood rack that I got for about $50 off Craigslist. I removed the items marked with a red X and then moved the trays outbound so that the wheels are cradled. I have a Nissan Frontier and the wheels stick out to the sides about 4 inches. I’ve driven from Denver to Vermont and back with the bike on the truck and from Denver to Lincoln NE and back. On neither trip was the bike difficult to carry nor did it come loose. I would suggest pushing the arm down over the stoker stem very tightly, however, and adding some padding to the foam on that arm. Pipe insulation from Home Depot works well.
