Flooring Under Dinette (Pictures)

We bought a brand new Four Winds Hurricane some 12 years ago and began updating the interior. We removed the dinette completely as we’re adding a corner chair there instead. We’re ready to start pulling up carpet to replace the flooring when we discovered that underneath the dinette table, the flooring is not level, it’s last an incline, like a ramp. Now I understand why it was impossible for two people to sit on one side of the dinette bench, because there was no leg room. They had a carpet pad on top on the floor carpet, so we didn’t realize the floor was like that. It’s also steel, so it cannot be removed. We’re trying to figure out why it was designed this way? The slide out is also not a straight line, making remodel more difficult. I’ve never seen a slide out this way in other remodels I’ve looked at. Any thoughts? And we’re replacing the floor with vinyl planks.
