has anyone modified the sides of the storage box on the roof so that you can't see what's in it? I understand the whole idea is to have it vented so that the smelly stuff has a place to breathe, but just curious to see if someone moded it. The holes (or vents) on the side invite strangers to say "hey something's in there an I want to get it". My thinking is if its modified somehow, it would be less inviting. Essentially, people non-familiar with xterra's wouldn't even suspect that there's a storage box on top. Pictures would be helpful.
