Reason not to use a two wheel trailer
I haven't found the three tracks thing to be an issue in the riding I've done and I've been on some very rough roads.
The road shoulder shown would not be an issue whether I was pulling a trailer or riding my road bike. I'd be riding slightly left of the white line.
I haven't had an issue with flats on my touring bike while pulling my two wheeled trailer. You will get a flat if you run over something that can puncture the tire and that can happen quite easily whether you have 2, 3 or four wheels.
Deciding between one or two wheeled trailers is really just a matter of preference unless you are planning to do most of your riding on narrow and rough tracks. Al
