Some trailers have 1 wheel and some have 2. Less wheels = less resistance, but more instability. Since the Katy is an old railroad bed, hills aren't much of a problem, but rolling resistance can be a problem: A wider 2 wheeled trailer will find the soft edges of the path and give you more rolling resistance, it will not trail the bike in the hard packed middle of the trail. It will also be more inclined to get a flat. But one wheeled trailers can be pretty expensive. That is a big expense if you don't plan to use it a lot.
I don't like either of them. If you don't have panniers, I'd suggest you consider going to Eddie Bauer and getting some duffle bags. Line the inside of the duffle with large trash bags and put your stuff in the duffle, and viola--waterproof cheap lightweight baggage you can strap to your bike. Get some cheap racks, and some parachute cord, and you should be able to carry as much stuff as you need to carry without having to worry about another set of tires and tubes that can go flat.
