It is more difficult to back it up because of the two pivot points. One at the ball and one at the front axel. Once a person gets familiar with this type of trailer it is more maneuverable than the standard trailers we are familiar with. I'd love to see an travel trailer with that configuration since it would greatly increase the towing capacity of the TV.
It is definitely not for the average driver and some drivers will not be able to master it.
