I have some pics of the Bus Depot heavy duty hitch compared to the Dennis
Haynes square tube hitch side by side mounted of a VANAGON.
If you want them let me know.
One main difference:
The BD hitch is hidden by the bumper and not seen.
The DH hitch is a square tube that mounts below the bumper and is seen.
These are much stronger than the hitches that bolt to the existing bumper
mounts.
