I haven't had issues with the skewer nuts but I 've only had it for a week now.
I like the idea of the can holding the trailer tire. What do you use, something like a tennis ball can? Do you include any tools (tire levers, inflator, etc).
With the forty-some odd pounds in my last posted trip, I noticed the bike is very sensetive to bieng tipped over.
With the mini lock-you are replacing one of the cotter pins with a lock so the trailer cannot be released from the bike unless you have the key?
