Would like to know how others are able to bake in their RV ovens and have success & not over cooked or burned food.? I know part of my problem has been using too big containers for oven. (such as 13x9 pan) Last year I was talking to another RV lady and she told me she had found a portable fan to put in the bottom of her oven and that solved her baking problems as it helped force the circulation of the heat around.? I failed to ask her where she got it and assumed I could just go into Camping World and find it - but not there.? I would appreciate any tips and ideas.? Thank You!
