I've used a BOB for several years, but will admit that I haven't done huge tours. I've done RAGBRAI using is rather than having anyone else carry my stuff. I love it. The trick to it trailing well is packing it right. If you get your heaviest stuff toward the front or high in the trailer, it stinks going down hill...gets very squirrelly. OTH, if you pack it right with weight low and as close to the rear as feasible, you can easily hit speeds in the 40's downhill (obviously!) and don't even know it's there.
