I have the fold and tumble seat and am thinking about the underseat drawer. Looking at the tuffy site and specs it looks like the fold and tumble version is about half the size of the other version. For those that have the smaller drawer do you think its worth the money and how much can it really hold? Is there a way to modify the bracket for the larger drawer? I installed a Mastercraft seat and the tumble feature no longer works anyway. Has anyone gotten one of these drawers to work on the passenger side? How does the Bestop drawer compare to the tuffy?
