Hi Sean,

Welcome to the forum.

It is hard for me to tell what was originally wood and what was metal in those photos.

Can you tell us a little more about how you think the basement floor was constucted. I know mine is all metal, except the floor under the battery bay.

In general I think that first you should look at the cross members to see how much cancer they have. If the answer is not much, I would take a sawzall and saw out one rusted section at a time, and mig weld a replacement sheet in.

Prime and paint.

Not an easy task, but not impossible either.
