A Nomad is set up to track off to the left. In my experience, unless you are riding within 3 inches or so of the shoulder(which is tricky), both trailer wheels will stay on the pavement. I almost never have a wheel drop off the side.
In my opinion, by far and away the biggest advantage of a two wheeled trailer is that the bike will handle almost as if it were unloaded. And the biggest advantage of that is that when you stand, like climbing a hill or whatever, the bike won't wobble and shake like it does with pans or a Bob.
