How much have you hauled in your trailer? I have never towed anything behind my bike. I've seen a few different configurations. Some folks have front and rear panniers -AND- tow a trailer. Does anyone here do that? How much gear-weight are we looking at total for gear on-bike and in-trailer? What is the most (weight) that you've seen people carry in their trailers? I'm gathering data for a future project, and I would really appreciate any info/insight/commentary that I can get. Thanks!
