Liz if I am not mistaken the Bigfoot
delamination issue involved trailers 25' or a bigger one? they made for awhile which were not molded fiberglass?
The smaller sized Bigfoot
trailers where then and still are actually molded fiberglass and built in a fiberglass mold so delamination wasnt/isnt an issue.
EDIT TO ADD: I think what Bigfoot
for a time use a system they called Fibercore on their bigger units and motor homes. Trailers that were build using that system have fibreglass caps on the front and rear edges of the roof.
