Installed a backup camera and monitor. Went with RVCams:
Camera: Voyager VCMS155
Monitor: Voyager AOM562HD
I knocked off JohnM's idea and install technique (BillW too) with the mounting plate using existing screws. John did an excellent write up of the installation here (Backup Camera Modification (http://www.foreforums.com/index.php?topic=29699.0). Anyhow, if you don't want to cut your dash and disable the light show this is a good solution. If you don't mind cutting it you can get a better look with a flush mount.
I had to insert some spacers behind the Javelina box in order for the BNC/RCA cable hookup to clear the doghouses vertical support. I'll dump the Javelina when the tank monitors fail.
