Yep...I don't use the dutch oven much anymore.
The boys have learned to bake rolls, cupcakes, muffins, biscuits, cookies, pizza, etc..
We have used the same oven for 2 years now and only just torched the cardboard this past weekend. I over heated it and was distracted with the rest of the meal.
Taping the foil with aluminum duct tape was the key to longevity.
