Because of the complexities outlined by M, I canned the idea of selling the bike or the trailer in the US. I brought them both back to Vancouver in November, and sold the trailer in December. Now, I got myself a Katana 600 and have my 2005 Ninja ZZR 250 (4500 miles) posted for sale in both Kijiji and Craigslist, asking $3200. As of now I've received a standing offer a little short of that, which I have not yet accepted. Also see the thread in this forum under Pictures, titled [My "new" bike and bike for sale].
