You might want to be aware this forum is specifically focused on all-molded fiberglass trailers- "egg" trailers like Scamp
and Casita- in which the entire trailer shell is laid up in one or more large molds and fiberglassed together to form a seamless, frameless unit. The distinction vs. conventionally framed or laminated trailers with a fiberglass skin is unfortunately not clear in the site name or web address.
All are welcome to hang out here, but you may not find the kinds of specific information you need for your rig. Seam maintenance, delamination, slide-outs: not in our vocabulary.
