I'll answer for him. He's using 3 aluminum angles across the front and back. It certainly doesn't really match up with the strength of his side walls, but I don't think it's really that flimsy assuming you have bumpers to spread the load. A corner hitting a single angle would definitely be bad, but with a bumper the load would be better spread over several angles and a larger area laterally.
