I found a picture of the cardboard oven.



We used the lid to keep the top closed since we made ours top loading. And if you look at the top right corner of the oven, you will see the thermometer.

Here's the huge roast that was made in the oven on that wet trip. If I recall correctly, the roast cooked in the oven for something like five or six hours. Just one propane canister was used too I think.
