WannaBeFree,
I see someone has posted a link to tadi brothers site...here's a link:
9-Inch Monitor with 2 Wireless 170° Mounted RV Backup Cameras
I use one of their 9" split screen monitors and two cameras on my grader...allowing me to see each lower tip of the mold board. The system was $438 for the monitor, two HD cameras and all the needed wiring. I purchased a system that is hard wired. I've had too much trouble with wireless systems around the metal on the truck and tool bed.
The screen will accommodate four cameras. I only bought two. But I can mount them on heavy velcro, run extra cables, which you can get from tadi brothers, an put mounts wherever you want on your truck, your RV...wherever.
Just thoughts,
Pirate
