I have been investigating class c motorhomes for my wife and I. I am surprised that even if designed for two people, they have so much "seating" and such little working and storage space for cookin...
I always thought one reason that kitchens weren't bigger, is that many, if not most people, do a lot of outside cooking and eating. As far as seating, my Forester front seats don't swivel, so they generally get used for storage/catch-all while set up.
