Exterior Laminate vs Aluminum

We are in Central Texas and get a LOT of hail (State Farm has replaced our 40 year hail resistant roof three times in the last 14 years). Our insurance agent said don't get a tin trailer here because it will just get whooped unless you keep it under something all the time. He said to get a glass one because they hold up a lot better in hail, and if they do get damaged very badly, they total them out and you go get a new one (as well as your home roof).

I have seen several trailers around here that have so many dents from hail that they just look sad, including an airstream that looked like a giant silver golf ball...
