I will probably go with this "mirror" add-on from Holoview:

The wireless rearview observation mirror dashcam system has a front-facing camera and a waterproof exterior rear-facing camera that looks perfect for any vehicle where rear visibility is obscured!
The display "straps" over the existing rear-view mirror; the rear camera goes where you need it and the rearview mirror monitor gets power from a cigarette lighter power outlet.
It records video (or takes still-shots) and has good night vision (infrared, baby!) from the rear-facing camera.
. . . and no gigantic extra monitor to clutter up the dash of a brand-new truck!
What say ye , fellas?
