We are learning the ways of convection cooking as well.
1st mistake; make sure you take the glass dish out of the oven when using convection. We shattered ours.
Other than my mistakes, the convection oven is awesome. Being able to brown stuff without a regular oven is extremely convenient. We look forward to finding new ways to use it.
My suggestion would be to watch some YouTube videos on RV convection cooking. That's what I've been doing...
