That really is a work of art and guys like me can appreciate all the work that went into it. If I was a big cruiser bike rider I would be very interested in something like this for touring with my K9 girlfriend. I often thought about a bike with a side car but they give me the feeling it takes the fun out of riding a MC.
The box I made, also for sale here, worked great for my 40 pound dog on the TW but would not do for long haul trips. Some dogs just love to go so you have to make it possible if yours is a go for a ride freak. Just yesterday I saw a video clip on TV of a very large dog riding 2 up behind his driver on a big Harley in the Queen seat.
