Real scoop on Fiberglass skin trailers?

Down to the wire on purchasing a new trailer. Brand: Jayco Jay Flight.
2015 offers both aluminum and fiberglass options(as an upgrade)
Do not like the frameless windows- too many negative posts on them.
Has the delam issue been solved or is it like all other laminated products and will de-lam in time?
Not sure which way I'm going but looks like the aluminum is a sure bet as it has been produced for ever and many are still running.
Any Flight owners w/ fiberglass??
Please share your pros and cons-

thanks
