My hangups with the campers aren't just with aesthetics. In the 70's and early 80's, this style of cab-over campers were really popular with my family members. I myself never liked 'em to begin with.
Nowadays, my own preference is to stay as light as possible with the absolute minimum of gear to carry. It's easier on the vehicle, easier on fuel economy, and I spend less time worrying about the arrangement of objects and all of their needs, eliminating some of the planning and preparation time, which is limited to begin with, required to strike out on a trip.
The other huge liability with these campers, as far as I'm concerned, is the cost and complexity of maintaining the shell and it's systems. Having all the comforts of home means maintaining a second one! It's all nice when it's new, but after 3~5 years you've got plumbing to worry about, appliances that often are dedicated to that company or model making replacement costly, roofs and windows to keep sealed and, I would have to believe, extra wear and tear on your vehicle. Let's not forget all of the various storage tanks to fill, empty, clean and keep inspected - sewage, waste water, fresh water, and propane.
