Convection Microwave - Reliable Brands / Models?

We have the Dometic brand that came with our 5th wheel and we are on our 3rd one all under warranty. The first and third one cook so off temp that it is about 100 degrees below the set temp. The second one just stopped in mid cycle. Dometic does not repair them, only replaces them. It is now out of warranty so we are going to replace it with a GE Advantium soon. For me, I have to consider the location of our current outside vent and the upward swing of my glass top stove cover. We remove the glass turntable and lay it on the bed. I used to put down a piece of non skid shelf liner and turn the turntable over. It was fine there until our trip to Alaska last summer. It came out, landing on the floor. It did not break , just a chip which is amazing. I would not recommend the Dometic brand. I think you can set up the Advantium to vent inside much like it would do in an apartment or condo,

I have a Frigidaire, but the GE Advantum gets good marks see this discussion

The Sharp model R-1875-T is installed in an awful lot of motor homes. We sure like ours.

if the potential mounting location is up high, convection/MWs put out a lot of heat so venting is essential.
