Query: Firmer and thicker than OEM

This seems better than the one that came with my trailer, which fell out on one of first trips. It still vibrates loose a bit but hasn't fallen out and seems thicker and slightly more riggid than the original, though still has enough flexibility to get it in the bumper. I only gave it 4 and not 5 stars because like I said it still vibrates loose a bit.
