Hi
Guess you will find a big choice of convection/microwave units at
www.appliancesconnection.com
What we built in:
A
Summit CMV24. A great microwave/convection oven made by Electrolux of Sweden in Europe. This runs on 240V/60Hz. It's 80lbs and you can have 10 years of warranty. We built it in counterhight (no more bending down or reaching up) and this is great, like at home! Price about $1050 (ok, that's expensive). It even have a "child security" (spring clip), so you can travel very well with it without a risk that the door will open.
Smeg has a
similar product (also Made by Electrolux), we have it at home, heavier, better, more design and certainly more expensive ($1700).
Why 240V instead of 120V and will it run in a coach? You have much more power to heat and bake and if you are on the shoreline (guess you have 50Amp service on your coach) it works very well. Those 240V appliances run on two 120V sockets (there are several youtube movies how to do it) but it's better if you talk to a professional who will install it in 10 minutes, direct line, no socket needed and a fuse. You can even run them on 120V too but then it needs longer to bake something.
Ok, this is quite a luxury version but let me tell you: If you like to cook, you will never regret your investment. We both like to cook (and to eat) and that's why I installed those appliances also in our RV. Good appliances are like good tools for craftsmen who cannot work with "cheap things". Our Smeg at home runs since 1997 without any problem and the Summit in our RV since 4 years, every day when we are on the road, no problem.
