I found a replacement convection/microwave unit for my Sovereign
that's working well. I've got the rig set up as "off-grid" as possible with a 200+watt 60vdc solar panel/4 x 6vdc deep cycle battery array/2500w inverter. The convection micro unit is powered by the inverter when the battery array is fully charged. Otherwise, I use the Honda 2kw generator.
Since my "oven" cooking expertise is limited, I thought the c/m unit would better suit my baking background and it does. Just know that the baking volume of the c/m unit is significantly smaller than that of a typical RV gas oven.
Hope this helps. I can send pictures if you want to see how it looks.
My unit is an aft bath/center bunk room configuration.
