I have an Eagle aluminum, but my buddy has a steel trailer.
Steel is fine, but you just have to take care of the surface rust, just like an old car or truck.
There are a lot of chemicals out now that make rust maintenace easy.
The chemicals mix with the rust and neutralize it and
some even turn it into a protective coating.
I think the old days of wire brushes and patch welds could be gone.
I just learned from our metalurgist about a steel that has copper in it, his words:

"Corten in the US steel version. It uses copper additions to impact oxidation rate and adhesion"

They are starting to use this stuff in buildings and bridges.
