I recently mostly restored one of these fine gems. They are not fiberglass. They are polyethylene. Did a frame off with de-rusting, primer, paint
, new u-bolts, gas struts, weather stripping, wheels n tires
, led tail lites, etc. The body had layers of sequins and paint
that were removed. I would say this is a real minimalist trailer. The gull wind doors are attention getters.
