I have towed both single and tandem, and I like towing the tandem trailers better. I like backing up single axle trailers more than tandems. Those will turn on a dime. The only thing about tandem axles is when making a tight turn on pavement I think the sidewalls of the tires really get a work out because two of the tires will kind of be dragging instead of turning.
