Your second link (to ebay) has the right picture but the wrong price.
This has the wrong picture but the right price. I think the basic Surco tire carrier is the TF200 for the ford van.

I have a 1995 and have mounted the Surco. It has advantages and disadvantages.
The biggest advantages are that it is cheap and simple.
The disadvantages are you have to drill 4 holes in your door and when you open the door, the larger tires run into the rear light (I have not broken mine yet-mostly just leave that door closed). I don't now how it would hold up to rough use but it is pretty robust/solid when the door is closed.
It is the opposite of the Aluminess tire mount in most ways but it does work well.
Once you move the tire out from under the van, you can cut out the big tire carrier and mount a storage box underneath.
