Tonight on Craigslist just saw TWO classic 1970s fiberglass 13' trailers, both apparently in working order! One i forget the brand but laid out exactly like my Compact Jr. (by Hunter Industries) and at a very reasonable steal below $4,000 !
The second a 1970s Scamp
with the bunkbed intact, so sleeps 1 more, also a fiberglass 13' er, that one less than $11,000 which is a more average asking price.
My recommendation is that if you have the slightest interest you immediately call and get appointments, pack your bags and GO see them. The cheaper one likely won't even last until the weekend, and the more expensive not too long.
Call me for my take on owning a Compact Jr. but only after you get an appointment as otherwise will be a wasted discussion!
