Here's a youtube link to an interesting camper with a
fiberglass roof.
You apparently supply your own utility trailer and snap these plastic panels together:
But what I found interesting and maybe of use to other campers was the pressurized water system they use.
It's just a plastic weed-sprayer bottle hooked up to the sink.
It's something I may investigate next year for my Compact Jr.
This trailer has a layout very similar to the Compact along with the pop-up
fiberglass roof.
