Looks like an awesome setup and maybe we can do a group buy after we can get more details asked above as well as:
1) Are the boxes absolutely waterproof and airtight?
2) Are the locking mechanisms waterproof and rustproof? - I don't see any protection for the key holes.
3) How do we mount the boxes to ensure security as well as longevity and no vibration?
4) Will standart BMW liners fit inside?
Don't get me wrong, I think could be THE alternative to the crazy priced BMW boxes that I'm ready to buy. It's VERY hard to ante up ~ $2000.00 for the 3 boxes and liners and carry straps though. If this product can be a viable option to the existing he'll sell a ton of them. On the other hand, there's nothing more frustrating than getting excited about a purchase to enhance your machine and then be disappointed by the performance and feel like you wasted your money becuase you were trying to help a new guy/vendor out.
