I recently toured hauling a trailer for the first time - Up until then, I've had the traditional panniers setup. I was carrying camping gear and supplies for my wife and I.
The trailer is a Burley Nomad 2-wheel cargo trailer I use for groceries, and it handled very well overall. I'll be taking it on tour again. However, I definitely felt the trailer's inertia, particularly when first pulling away. Downhills weren't as much fun as they could have been. Oddly enough, I found climbing to be a bit easier than with a loaded bike. Weird since I was carrying at least 25 pounds more than I normally do (counting the 15 pound trailer).
Those of you that have toured with a trailer, what wisdom can you pass along? Pictures, as aways, are awesome. How much time do you put into packing your trailer? Do you keep the heavy stuff in back, up front, what?
