This mount was the product of Hurricane Sandy (and no power in my house). I sat around for a few days trying to think of a minimally invasive way to attach a semi-permanent camera rig to the cab. I didn't want to use clamps, or have to drill any holes, basically no mods or potential for damage to the cab. The mount is held in place by the rubber feet, resting on the marquee and by two of the marquee retainer screw holes. The adjustable neck (taken from a dead desk-lamp) is attached to the threaded camera mount on the lifecam via. the correct size threaded bolt and some rubber spacers. I can disconnect the swivel neck and camera from the mount instantly, which is good for filming verification on the spot. Also, because all of the marquee retainer screw holes are equidistant, this mount could be moved to the left or right of the cab if desired. The best part about a center mounted camera, is that you can capture a very symmetrical image. If you can get the other settings right, it will essentially look identical to mame, as far as clarity and image symmetry are concerned.
