The bed should move out of the way so the room could be used for living activities when not sleeping. Either Murphy or to the ceiling like Trek. Unfortunately, the Trek bed is at a height my wife can't comfortably use. Wouldn't have been a problem a few years ago.
At least 90% of the Class A's I looked at before buying my new one had the TV in a virtually useless position. Why have the captain and co-pilot chairs (often the most comfortable seat in the RV) rotate if they don't look directly at the TV. It would cost less than $50 to have the TV swing so it could be viewed from most seating in the coach. Very few do.
It takes a lot of looking!!!. Been doing this for over 50 years and I'm convinced that marketeers tell the designers they need a TV, couch, dinette, stove, sink, microwave and refrigerator. The designers have NEVER used an RV and simply check off all the boxes. Most RV salesmen I have encountered are just like the designers - even less competent than computer sales persons. Occasionally the designers do get one right, but it takes way too much looking.
Slides that obstruct the use of any critical component (to you) when closed are a no-go red flag. You will need to use that component, and not be able to extend the slide, some day.
Important caveat: I was looking at Class A's 30 feet and under due to driveway issues.
