Many have had hitch recepticals installed, bought a little trailer, and done fine towing tandem. I have a friend who lives near Salem, Or. and he tandems all over the place, Washington, Idaho, Montana, California, Nevada,Arizona, New Mexico, and Texas that I can vouch for for the past ten years. He has never been stopped, questioned or had any bad experiences. A former California Highway patrolman two weeks ago told me that even where it is illegal, the highway police ignore the practice. They are not familiar with laws that are under the jurisdiction of the state DOT is what he claimed, so even if they see you they leave you alone.
Reading these boards it is rare you ever hear a member say they were hassled for tandem towing. Anyway, I would go the small trailer route if I were you. I have thought about the same myself and will stop by a welding and fab shop to see about getting the hitch system installed this summer.
