Re: aluminum and galvanized traiker
I think that aluminum and galvanized have become more reasonable in price over the years. Along coastal areas, but slightly inland, people would try to get away with painted trailers. It was risky. But since the alum and galv prices have become more stable, it's easier to justify getting one instead of painted.
Far inland, far away from salt, I still think painted trailers rule the day... especially after navigating 11 bajillion boat ads in which I pursued a non-salt-water boat on the slightly used market. Man... it's 99.8% painted inland.
