I had a pair of those folding ones, rated to handle 1500lb. My Razor weighs an even 1000 but one of the ramps broke a couple years ago. All 3 rails sheared off right next to the hinge as the rear wheels went over it. Luckily, the expanded aluminum held until I could get the Rzr all the way in the trailer. I now have a set of solid ones, rated for 2500lb.
