BTW, the hitches I offer can handle 5K, 400lbs for the frame mount or 3500/300lbs tongue for the Dalan - both are class III. Mine mounts to the 7th ladder of the frame, the Dalan mounts below off of the 2 frame rails.

There is a more leverage at work on the Dalan but psycho moves way heavy boats with his all the time - be sure to check for cracks in the welds if you move weight like that.
