Kingston! Well Made and Solid!
I have found them to be very well made, solid trailers. You don’t see them being sold everywhere since the company only allows so many authorized sellers per area. I often had the use of a 2003 Kingston bumper pull before moving south. I remember the ramp being very easy to lift, of solid construction, and all of the closures for windows, doors, etc were user friendly. It was also very light and airy (ie welcoming) for the horse and easy to pull for the driver. They also hold their value very well if you ever needed to resell.
