Thanks! It actually came out better than I expected. I didn't think the suction cup would work at all, but it's very stable.

I actually had something like that planned for my mount, but it made things more complicated, and would require a much longer U-bolt, which I simply didn't have "in stock" last night.

The rear mounting point has 3 purposes, it has to resisit yaw, pitch and longitudinal movement. The connection at the child saftey hook really only pulls the mount down to the deck, so at that point the mount has quite a bit of movement. The seat and the rear cup are really what keeps the mount planted. The only direction theis mount isn't very stable in is roll, so if you've got a camera that's weight isn't very centered on the mount, it will translate into bounce. Your suggestion of some 90deg cross braces at the rear and near the seat would help the stability a lot, but would also mean all the yaw and lateral support would be entirely from friction between the braces and the rear deck. I wanted at least two "fixed" points in the mount. You can see what I mean when you see my mount. It's actually screwed in under the brake lamp on my car. Matt's mount was basically a version of my mount redesigned to work without the brake light.

As I said above, this mount makes no holes anywhere, it's connected to the center child saftey seat hook.

I think this is a good idea, and coupled with the T at the front behind the seat, I think you could have a very stable mount that doesn't push the seat at all. I'm just concerned with the bulk of the mount in the rear-view, and the lack of two distinct fixed mounting points.

That's cool, I'm unofficially sponsored by Lowes, so I get all my aluminum there.

Take a look at mine and Matt's in person. I'm sure it'll help you with some ideas and help you to improve on the ones we made.
