I've tried searching the Interweb, but can't find any info. I'm hoping someone here can provide some (admittedly trivial) info.
In the early 1970's we had a family camper that I remember as being made by Fisher (of snowplow fame). it was a steel-shelled pop-up Aframe that weighed a ton (more actually). When set up it looked like a current a-liner or Chalet
I can't find any evidence that any such camper ever existed on the web.
