Obviously your excited - Good for you!
One of the first things I added as well. Consider first what you expect it to accomplish for you, and placement.
I made the mistake of opting for a Licence plate frame camera. Great picture, but I wish i installed it above the back doors so the tire & rear box were included in the view - proximity of these are left out when the camera is mounted low...now I find myself having to incur additional expense by either adding another or moving the existing one.
X2 on camera up high as you can see trailer your pulling as well!
