Class A gas - fiberglass roof? Who uses them?

Watch AZ Expert on Youtube if you are looking at used Winnebago class A coaches, he was a Winnebago RV tech for a number of years and has dozens of videos detailing issues with their fiberglass roofs that he has had to rebuild. If buying new calling manufacturer directly should yield the best coach specific info making it easier to decide which manufacturer provides the roof material you desire. Our current class A coach has a metal (aluminum) roof, although it has well over a decade of heavy use and full exposure to the elements over its lifetime, it has never leaked and still looks pristine. We have had every type of roof material on the 4 RVs we have owned over 3+ decades of RVing, upkeep is paramount regardless of material used in roof construction. Have fun shopping, hope you have many great experiences RVing, although it can be challenging at times we just love getting on the road with our motorcoach.
