We have a steel rugby flatbed on our old 3/4 gmc & we're looking for a flatbed for our new 3/4 gmc & checking out our options. I'm assuming the weight savings is on the aluminum one, but it is more expensive. The steel flatbed after a few years looks horrible. Ice melt & salt are torture to it. Would an aluminum flatbed hold up any better? The look of aluminum is so much better than black/rusty steel. What are their downfalls besides price? It seems that %95 of flatbed are steel. Why arent more guys running aluminum?
