I think MadJack used aluminum angle on the inside to secure the floor and walls together. You could route the bottom inside of your walls to hang down and cover the frame. I welded some tabs to the bottom of the frame to help with shear loads. You can see them (barely) here. http://www.tnttt.com/gallery/image.php?image_id=2067
Bottom right of picture. It's painted so it's hard to see. Look for the dust on it.
