Looks like the ribs won't be an issue installing a center drain for you as I went out to look at my tank that is not being used for the winter, and the ribs do not extend to the center. I also didn't have any significant issues with solids trapped against the ribs. when in use.
I'm wondering if my tank wasn't made in the same mold as the ones you're looking at as the measurements seem the same width wise and depth wise.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
