Many of the transport guys use enclosed trailers. First time I used usurp is when I bought my K4 out of KC. Bullet Transport was his company, he had what have must have been a 40 foot trailer, very nice rig. He had no less than 10 bikes strapped inside and had to move a couple to get mine out. I don't remember specifics, but all the bikes were very nice, a mix between vintage and modern bikes.
