As far as I know this chicken has to be cooked using indirect heat. That's pretty easy to do on a regular home grill. I think it should also be reasonably simple on a camping propane stove or even a campfire.
Stove: I'd say it requires a two burners stove and removing the 3 side panels. Put a large grill on top of the stove, start the burner on one side, put the chicken on the other and cover both sides with a large inverted pot. One could even give it a woody taste by putting a handfull of wet wood chips in an aluminum foil and put it on the side of the running burner.
Campfire: I'd use one of those fire rings available at camping gear stores. Make sure it's leveled and solidly seated on the ground, that gives you a nice leveled support on top of which you can put a large grill. I've never used one of those rings but I guess they are large enough to make the fire on one side and set the chicken on a beer can on the other side and cover it with the pot. The heat source could either be a fire or charcoal. The only problem I haven't solved yet is that the fire won't last as long as charcoal would in a closed grill so I need to find a way to "feed" it. I was thinking that I could cut a hole in the grill on the side of the fire through which I could add small logs but I would have to remove the covering pot and the heat would be lost. Maybe the solution is to use something rectangular instead of a pot to cover the chicken, it would leave room on the front of the grid where I'd have the hole to add wood logs.
I'm always amazed at how much thinking we can put into something just for fun and have good time and meal with friends........I'm sure my boss would love me to think that hard at work
