The problem you will have is that the furnace will be in the way. In the Overlander, I think they mounted the oven in the wall because of that reason.
You need about 20" wide, 21" deep, and 24"-27" tall space (I think).
is a picture of the space in my Sovereign
. The furnace is located to the right (under the sink). In the Overlander, the furnace is to left of the sink (below the stove top).
If you don't care about the furnace, you could remove it and probably make enough space for what you want to do. However, I can't think of another place to put the furnace.
