Any ideas for a DIY oven post shtf?

i've used the dutch oven some. with practice you can regulate the temperature a little. patience is key. dont put it in the fire. put a few hot coals under, and a couple on top and wait. you can practice with charcoal and put a oven thermometer inside. having said that, would be nice to have a bigger oven. I've checked out the coleman's stove here, didnt buy it cos looked kinda flimsy.
