Well spoke a little too soon on the rust
Pulled up the floor mat and what I thought was good looking metal before turned out to be some kind or insulation. While not horrible it's still more than I thought. Was hoping to not have any floor patches but the driver's side toe panel has about a quarter size hole, passenger side toe panel has a bad patch and more rust on the floor board right at the "seam" where it angles up towards the firewall.
I'm not discouraged as I was expecting some of this stuff. It makes the idea of buying a new cab appealing but where's the fun in that?
