I really can't tell from the picture, the near side looks like the ford frame rail, but the inside of the far rail looks different. Most of the manufactures extensions look like Dales pictures, square edges at the bends, not roll formed. Most manufactures extensions are really a cobbled-up mess of steel with some ugly welding.
My hitch is on extensions and it would be a rare (not saying there are none) Ford chassis that didn't have extensions once a builder gets done with it. All F53 chassis are delivered with same rear overhang of 105.8 inches from rear axle center to the end of the frame.
Looking at the pic of the failure it is apparent that the hitch is attached to house builder added extensions. You can see the Ford frame on the right side of the edge near the fuel tank. Also in view is the last frame cross member. Of note is the frame section height is 9.2" at this point. If you follow the rail to where it disappears behind the hitch (Blue Line), when it reappears the lower edge (red line) of the rail is now several inches closer to the floor of the coach. Also you can see how the extension is bend on the far edge of the hitch (yellow line).
