I used a Mayacycle trailer on my trip and really liked it. The good part is that the weight was never an issue. The bad part is that itīs too easy to take too much (it doesnīt take long to discover whatīs necessary and whatīs not). I never had an issue with fishtailing, etc, but it took me a while to figure out how to distribute my load. Going down moutains could be hairy, but it wasnīt because of the trailer but because I was still in the learning mode and was scared of speeds over 22mph or so. The downside is that you have to have an extra tube and wheel, but the upside is that once you get moving, youīll barely know itīs there. You donīt have to unload all of your panniers to just use the bike. Unhook (under a minute) and youīre free. As far as whatīs the best trailer, itīs really personal preference. I got an amazing deal on my Mayacyle and have never regretted it. Others swear by the Bob, etc.
