Welcome, I haven't seen any recent updates on the fiberglass body version and not even sure anyone can give any more insight or info on the potential longevity of the fiberglass version since they haven't even been released, or have they? Are they even still planning to make them? That being said, there seems to be several nice used Ford E350 SMB's for sale, some are posted up on the forum, that might be a better route for you. Check SMB's sight for used ones too.
BTW, in the future you may want to include a posting title other than your forum name, that way we can at least see what the thread is all about.
