Got a nearly-new Nomad, and everything is fine

For real, though. It's great for me and my riding style. I'll go way out of my way to avoid busy highways with narrow shoulders where possible, and I putter around and meander a lot. That right there negates the two more serious drawbacks. The trailer does slow me down, but I feel less worn out at the end of the day - I think it's because I don't have to constantly balance panniers. It's easier to stop and park, and I don't have to worry about stressing my rear wheel or frame. So far this'll all go for any two-wheel trailer, but I vastly prefer the design of the nomad to the quik pack 'big waterproof bag in a cart'. It's a lot easier to get into and arrange your gear in. It's not 100% weatherproof, but it airs out and doesn't get that rubber-and-sweat stink. Water coming into the trailer will most likely come from the bottom, from splashes or fender spray, so a tarp under your gear solves the problem.
