How essential is an oven for fulltiming?

I am opting for a cooktop only and a convection microwave in my next RV. I have an oven in mine but it hasn't worked for years and I don't miss it at all. Right now I store pans in it. I bake everything we could possibly want in the convection oven, and lately have started baking on top of the gas grill. Makes fantastic biscuits and rolls without heating up the RV in the summer. The secret is to use two pie pans, with an air space between them...in other words the pan with the rolls is larger than the one it sits in. That keeps the bottoms from burning.
I have a friend who uses her RV oven all the time, so it's just a matter of preference.
