There are currently 5 Hunter Compact's & Campsters listed on fiberglass-rv-4sale.com, several in So Cal alone. The newest listing is for a nice Compact-II that includes a real loo.

They are under "Other" FGRV's
Most of these, originally, were designed to fit into a standard garage and can weigh well under 1500 lbs.
Note: Some older listings may be "Sold", but two are new within the past 2 days.
Good Luck Hunting....
