We full-time RV and I had a lot of trouble with Convection Ovens. The Advantium 120 does it all and it doesn't heat up the RV. It will grill a cheese sandwich or a steak to perfection. To steam vegetables, I push Microwave-cook-by food type-fresh vegetables, the oven does the rest and my vegetables are cooked to perfectly, not under or overcooked and a vibrant color. Now I can finally make anything I want, garlic bread, bake a cake, you name it.
