Yes I have always wondered why there is not a nightstand in the slide out that also has the bed in it. It would add to the storage, and square footage of the bedroom.
I also wonder with all these roomy slide outs, why they never seem to put one in the rear wall of the RV? I have seen beds that slide out to the drivers side, passenger side, and most are only about 18" deep, while some are as much as 24" or even a rare 30" deep slide out. But if they used the rear wall, made the slide about 7'6" wide, they could put nightstands on both sides, and slide that thing out about 4 feet - if they wanted to!
I think the limit is how far the slide must come in while in the travel position! With a murphy style bed, one could have the bed fold up and out of the way, then the slide deploy once parked, and could turn a 36' long gas RV into a 40' RV by having the back wall slide WAY out! Have the RV designer never heard of a closet pocket style pocket door? They could have a 4' deep sidewall slide into a 2' deep pocket, and only slide in 2 feet into the living space.
So I guess not enough legroom for the driver when the slide out wall for the drivers side living room is to close to the drivers seat is my pet peeve!
Back when my RV was new, in 1997, getting to the bathroom with the slides closed was a challenge. So using your own bathroom while in a RV rest area was impossible without opening the slides. Also some floorplans limited access to the refrigerator. Not to much fun while full timing, and wanting to stop at a grocery store while on a trip.
Alpha used to build their RV with a 4' deep drivers side slide out.
Another RV manufacture brought out a 'double slide out' with a 2' deep slide out and another 2' deep slide out inside the first one, so it would slide out a total of 4 feet. They built a handful of RV's before going bankrupt in 2007.
What I hated in the RV I was looking at was the dinette. I ordered mine without one, and it came with three captains chairs on the passenger side, two 'extra' behind the passenger seat. I removed the center one, and the 18" wide snack table, installing a 29" wide X 44" long table in their place, that folds into it's stand on the wall. So I get to sit in a very comfortable captains chair while eating my dinner and watching TV at the same time. Those on the couch have to look sideways to the overhead TV, and the one sitting in the drivers seat or forward passenger seat really have to crane their necks around to see the TV, but I am very comfortable. Can even lean my seat back!
Good luck on your RV search. My buddy's Country Coach has a $1,200 Brookstone recliner in it, with power massage. Not a factory option at all!
