I always thought those looked cool. The step would be useful, but I also always considered the extra weight to drag around. If you can live with your car being exposed, an open is a breeze to deal with(no pun intended.). If you go enclosed, get one with a winch or plan to add one. All the enclosed ones I was involved with made life better by winching in. The ones without were super unfun.

For the money and used ones needing tires and/or brakes, plus the high resale on used trillers, I’d seriously consider buying a new one.
