We had a Raptor 3612, standard 102" wide trailer, and two Polaris Sportsman 500 ATVs, each measured 48" meaning it would fit, the challenge was that I loaded stuff in front and still had to get them in the rear doors, the rear door opening was just about 98" wide. The other challenge was the fuel filler line box protruded into the box which would cause the ATV to lean to the center and cause loading problems. I picked up a set of plastic ramps for doing oil changes with and cut one to fit over the fuel line protrusion and placed the other in the center of the room to pull the left ATV front tires up on, keeping it centered. When I loaded the second one I used carpet squares to protect the ATV from the door and the side of the toy hauler. It worked out, no scratching and just enough space to fit. Measuring everything is key, if you can pull one forward some it will help loading the second one in a tight space.
