replaced stove
When I first got my 07 I decided that I would seldom use the microwave, as we dry camp a lot. Went to a RV parts place and ordered a stove with oven. Simple to replace, remove top (gas connections, etc), remove wood separator between stove top and microwave, remove microwave. Put that stuff in the barn. Microwave is usable as a desk top unit, has mounting brackets, etc that are removable. Then drop in stove unit, and hook up gas etc.
Pretty much plug n play, nothing complex. Think HiLo was made for stove with oven, and microwave was an afterthought. Same size hole for either, just add the wood separator. Did that in 07, so don't remember the details, sorry.
