Thanks for the info.
I just spent about 10 minutes looking at their site, including the "video" and, unfortunately, the only additional things I know now are:
1. They are in Canada
2. They mount using the body mounts
3. They are aluminum and use stainless hardware
4. It's taller at the doors than under the cab. (it's deeper than I thought)
5. Their website is pretty, loads slowly but tells little about the product. (no length, width, depth, height, thickness, weight, color options, door sizes, weight limits, etc. )
The website creates more questions than it answers.
AND... . I still have no clue as to the price or even price range. Since they boast about their CNC manufacturing and the aerospace quality I'm going to make and EWAG and say that they are somewhere between not cheap and overpriced.
I think this is a slick idea and I'm picturing my towing gear being stashed more conveniently using this type of compartment instead of "up and over" the sides and into the toolbox.
