A simple saw horse design, up sized for your needs, out of metal, with a couple three chains and S hooks to hang from. Seems simple to me...
You could make it with a crank to raise and lower the pots it could be simple or as complex as you'd want to make it. A welder and supply of various types of steel, the possibilities are endless. Go talk to your local fabricator.
I was just thinking about you Jayme cause MJM gave me an idea and I thought of your skinner. On my firepit I could weld square stock to both sides, weld round stock to another section of square so it swivels like the skinner, use S hook and chain to set height and I'd be in business at home.
I like the sawhorse idea for when I get out and about. A lot of great ideas, keep'em coming!
Danny, I think I'd like a tripod when only using one oven and I like those horseshoe stands SJA posted. Maybe one of each might work too.
