Obviously, Filon has advantages but I believe those advantages all concern the builders and not the end users. I know my 915 Lance which I've sold had issues with the Filon cracking at the juncture of the side and the lower skirt and there was no way to really repair it other than fill the crack with Dicor. Additionally, Lance split the side skirt horizontally and added a plastic welt that was prone to leaking, very poor design. I see they have eliminated that now. Aluminum skinned or glass is the way to go, if, you plan on keeping it a while.
