I think the originator of this post asked for comments both positive and negative. Perusing down thru the comments, all I saw were enthusiastic positive replys.
Let me say that first of all, I have (no) personal experience with bike trailers......but I must pass on a scene I happened upon in '03 on the interstate coming back from the HD 100th annniversary celebration in Milwaukee. An Ultra was upside down on the shoulder of the road, the rider was face down in the middle of the interstate and was damn lucky following traffic didn't run over him before getting stopped. The riders bike trailer (still attached to the bike), was upside down too and the wheels still spinning when I got stopped.
Anyway, he came to and survived and couldn't figure what had happened, but the car driver running right behind him told me that the trailer started fishtailing and it just threw the bike out of control and the rider was flipped off in an instant.
Having seen boat trailers and cargo trailers fishtail before, it's usually the result of insufficient weight on the tongue of the trailer.....(should be 10% or so as I recall). Anyway, I figure he had the trailer loaded incorrectly or overloaded and/or the hitch came loose. I don't remember if the trailer was still attached by the hitch (upside down) or hanging by safety chains..........In any case, the whole scene kinda soured my desire for a travel trailer behind my bike.
