Aluminum vs Fiberglass TT

Personally, I had a fiberglass Class C before we bought the aluminum side travel trailer we have now. We live in AZ and the sun just bakes the fiberglass. It will eventually start to yellow white fiberglass here (anywhere hot or a lot of sun). I like the looks of the fiberglass, but it doesn't make sense for us here. I have a theory that the manufactures are starting to change the color to the off white because of this so it's much harder to notice. Either way, my aluminum side travel trailer looks nearly as good as the day I bought it. I don't stress about having it waxed every year like I did with the Class C. I know some people have issues with dents on the aluminum, but I have not had that issue. I keep my trailer in storage and I can tell you there are a lot of trailers in there that are fiberglass that are yellowing badly and have a lot of delaminaton bubbles - really big ones on some trailers. Everytime I see one of those or hear about it on the internet it makes me glad I went aluminum.
