Not totalled but dang, the floors in the Camaro were cleaner than that when we pulled it down in 2008. Your truck looks pretty clean. I'd be surprised if that's from wet feet but you're right, I know nothing about daily driving in snow.I looked carefully, I don't see any obvious leaks. It appears to mostly be where the driver and passenger's feet would be. No puddles, just damp. I'll check it with a hose before I put the carpet back in.
Don't worry Jared, i know that rust might be totalled by Texas standards but this is what we consider light rust in PA 😁
