This happend to me one Sunday when I was roasting a duck for dinner. Fortunately, parked outside my back door, I have a motorhome with a gas oven, so I quickly transferred the duck and cooked it in the van. I mentioned this on a caravanning forum and someone who obviously had just eaten some sour grapes replied that 'it must have made all the expense worth it'.
Replacing the element was fairly easy.
BTW, I don't like pizza at all. I've even tried one, cooked in a proper pizza oven, in a small Italian restaurant in Italy, but I still didn't like it. I suppose that if I was dying of starvation and pizza was the only choice, I'd eat one.
