Guess it depends on how one want to count. I would not count the Ready Brake as one extension. For me, I'd go with the dual extension. However, I make one caveat with this recommendation. One needs to consider installing the Blue Ox bracket(s) that clamp on where the receiver and extension(s) join. The look like "U" clamps. This will prevent the slop between the male and female from causing swaying and stress.
