Pros
  • Caster head keeps centering the trailer, quietly and in any weather
  • Rotating brackets mean no snapping up tensioned spring bars by hand
  • Sized for light trailers up to 5,500 lb, so they do not ride stiff
  • Limited lifetime warranty
Cons
  • Costs about twice what friction hitches of this size do
  • Needs a coupler welded on top of the frame with no tongue cross members in the way
  • Blue Ox does not say whether a ball is included
