Best recommendation is "Take your pick"
Actually I have one better one.. If it says LG upon it.. Pick a different one.
Depending on the microwave (I used to have a Tappin at home that needed NO modification for use in an RV) the only special thing is how it is vented, Microwaved DO need to be vented The Tappin I had (no longer made, I mean I got this puppy over 30 years ago, and it lasted 25 years) was front vented so could be enclosed in a cabinet no problem. Some vent through the top, or side, or rear.
These latter ones will have some added sheet metal (or need to have some) to duct the high moisture air to either the front, or out the back wall, where it won't rot the wood of the cabinet.
Home is where I park it!
