I started on the mods that were done to our 2004 28' CCD at Jackson Center.
As far as location, there don't seem to be too many choices as to where to put the microwave. I don't beleive the 2005 units had the roof locker over the dinette because they added some vista-view windows. Our 2004 did have the roof locker and it could have been modified to put the microwave over there.
You COULD replace the gas stove with a 3 burner range and a convection-microwave but if you boondock, you lose the benefit of a propane appliance.
