Camp Lite Livin' Lite question -- new fiberglass sides

They are building the fiberglass side units as prototypes for a possible sub model. Not sure of the rationale behind it, but they continue to manufacture the aluminum sided trailers with no announced plans to switch to fiberglass only. I think they are looking to come out with a lower cost line that still has the benefits of no/minimal wood, without discontinuing the current line of aluminum sided models.
