On my way to work today I saw a 5er towed by a Ford F-350 on the back of the 5er ,they had what looked like an old ,Bolt to the bumper tow along trailer with the single castor type wheel in the center of the platform. The wheel tire combination was about 13" dia. I didn't get a chance to stop and look to see how they had the whole thing set up. On it was a full Dress V-Twin motorcycle.
Just passing along someones solution to the question of "How do we take the Bike along?".

Hope this helps those with this Question.
