Oops! I forgot that the previous conversation was in another thread.
I had came up with this idea when after installing a 7" monitor to use with my VMSps engine monitoring system. The main screen on the laptop is used by the wife for the GPS software. The monitor had 3 different types of hookups. How could I put these features to a constructive use?? I am on my 3rd RV, the first being a TT, the next was a 5ver, and now the MH. The only way I have ever damaged my RV was to misjudge, not see, or get forced into an overhanging obstruction.
That was usually a tree limb in a State or National park that was in need of maintenance. Once was a low hanging sign that I thought was high enough. In each case the result was usually significant, and always expensive. The camera idea actually was hatched when I had my 5ver. But then I did not have the means to mount the camera on the top of the 5ver and see the image in the cab of the truck.
The camera will specifically be used when pulling into camp grounds or other areas with questionable overhead clearence. I would rather back up and screw up traffic then risk damage to the MH. A quick push of a button will switch from my engine software program to the forward looking camera mounted on the roof. If there is ANY question, then stop and look closer.
The camera was pretty inexpensive from RV Cams.com. If what I have spent in time, grief, money and flustration in the past can be eliminated with this mod, then it is worth a hundred times the cost!!
