Forest River, Winnebago, Coachmen, Fourwinds/Chateau/Dutchmen, Gulfstream, and Fleetwood all made a rear queen, split bath, mid kitchen, and front sofa floorplan in the late '90s going into the early 21st century. Most offered it with dinette opposite the sofa, it was the "big" C in rental fleets. You will find it in "base" or rental special (like Chalet, Majestic, Yellowstone) model lines, but not in upscale lines because those were already slideout models.
Fourwinds and Forest River continued making such a model into and beyond the 2008 RV industry collapse, again mostly for rental dealers, while some of the other brands dropped non-slide and low-priced models. (Only people willing to spend more were shopping, kind of like the car industry shrunk to luxury models during the depression).
So your brand choices start to dwindle as you looker at newer Cs, if you really don't want slideouts. But what you are looking for is out there, big numbers as ex-rental.
