+1 On the other hand, a 2 wheel trailer makes riding off-road...if it's important...much more difficult. I've done rides off-road with a 2 wheel trailer and it's a whole lot tougher. A single wheel trailer tracks the bike while a two wheel trailer follows a different route which makes picking lines much more difficult.
