I am looking for opinions on what is the better choice as a supplement to a 2-burner propane stovetop in a 13-foot egg, a microwave oven or a convection toaster oven.

Whichever I get, I likely would not permanently install either. It will ride on the floor while we are in transit and sit on a plank over the sink when we’re cooking.

The question is, what have you great cooks decided are the pluses and minuses of each? (I already know cooking a good steak in a microwave is a near criminal act, and you don’t boil a cup of water in a toaster oven.)

So, if you had to choose between them, which one is the chefs choice?

Maybe a dutch oven.

I have a friend that fulltimes in a 30' aluminum trailer. He has a gas range with an oven that he does not use, and he got rid of his microwave in favor of a Convection Oven. He says that he would be happiest with just the gas cooktop and the convection oven.

How 'bout a combination convection/mickeywave? I had one of those at my old house... I will have to admit it was probably too big for my Casita, but I probably bought it 20 years ago (and it's still in service, now at my sister's house!)

Here's one that's smaller than mine was (is):

I found it just by googling for combination convection microwave

That decision is for you to make based on how you would like to "cook" while camping. Are you a heat-n-eat or "cook" person? I'd be lost without my microwave and can get it to do just about anything I need/want (including browning), but others wouldn't want to spend the time to learn or the effort needed.

I'm with Mary... I had a combo micro/convection and loved it! Gave it up tho because it took up too much counter space in my new house... went with an over-the-stove micro instead... but, sigh miss the convection part...

Have you considered a microwave and then get a small toaster oven...the kind for toasting bread/sandwiches?
