Supposedly, the one shown by Drew works on 47-55 1/2 ton trucks, using the 1954/55 pickup rear bumper?

It is odd that they say they also have "a suburban version and a carryall version". Most likely this also uses the 54/55 pickup bumper.

Too bad they do not show more photos of installations.

If anyone gets one of these bumpers, please post an installation report.
