When I put the larger access hatch in my 19, I put the hinges at the bottom, and it was much more convenient to use than when hinged on the top. On many trailers they swing to the side, which is not too bad either.

I can see the hatch setup Jim Bennett shows as working well enough. I had a bottom hinged hatch on a fold down tent trailer we owned. There was a chain which held it horizontal when open. Worked ok till I put too much weight on the door one time too many. Screw pulled out of the aluminum inner skin. Easy enough to fix and I learned my lesson. Don't put a 12 pack on the open lid. All three of the hatches on our 19 are top hinged and keyed alike. That's such a joy that it's good enough for me. Nice access to all storage from the outside. Packing for the Mississippi Rally this AM. Refrigerator ought to do real well, it's only going to be 61F here today, cloudy and windy. Fall is in the air.
If I remember correctly, the one on the demo unit would snap shut if positioned anywhere other than fully open as in the picture. I guess that's an improvement since you can leave it open while you open the hatch and then snap it to the hatch.
