I am looking for one too. I am a Cubmaster down here in the DFW area, and have recently got back into camping. Cooking for several people requires significantly more organization than I am used to!
In the alternative if it does get sold - could you take detailed measurements of it before you get rid of it? One of our leaders is a pretty skilled wood worker, and I hope to convince him to help me work out the details. I have been working on a rough set of plans to make something similar, although a little bit bigger than the Campmate. It would also make a good project for my son in a year or two when he graduates into Boy Scouts, and can make his own patrol box for the Troop.
