whenever i am ready to order my smb (target date: 2009, fingers crossed) i will specifically stipulate that that roof be dead flat and not hold water IN WRITING on the purchase contract
IMHO, too much flexing of fiberglass weakens the integerity of the structure, again, IMHO ONLY...
i have never seen flexing with a fiberglass boat hull, on a fiberglass bike, or fiberglass panel on a vehicle.
going further, never seen a fiberglass raised roof on a van with a sag in the middle.....
maybe we should run a poll on who has a smb (penthouse) roof with a sag in the middle....to see what is the norm?
