Jayco Redhawk..are they worth it?

A fiberglass sounds great but we purchased a Minnie Winnie in 2014 because the roof was one solid sheet of fiberglass. It leaked the first trip, dealer did "smoke test", found nothing. Side seams were sealed. Six months later, another leak. Once again, seams, front cap, clearance lights sealed. Lasted about eight months. I now carry sealant and caulk when we travel. Winnebego didn't help, other than agree to look at it if we carried it to the factory. Dealer charged two hundred dollars each time they sealed the seams.
Brother in law has rubber roof trailer. Has it cleaned and resealed annually at Camping World. It is a 2012 model and has never leaked.
If a buy another RV, it will not be a Winnebago product and probably will have a rubber roof. Just my thoughts.
