Our Phaeton came without a gas oven but with a convection oven. I thought that would never do, although I'd never had great luck with the ovens in the RV's. But I soon found out that a convection oven IS a regular electric oven with a fan that circulates air. That's it. Because of the air circulation it's normally a little more efficient and sometimes adjustments need to be made. But on mine, the only adjustment is to use the minimum cooking time. Easy peasy. When we built a Texas room at our winter roost, I put in a convection/microwave oven. Works great!
