I am thinking about getting a wireless back up camera.
I have seen one at Wal Mart.  I think it is called the whistler.  Is anyone familar with that one or what do you have.  What do you like or not like about it?  I want something that is not complicated.

For your tow vehicle, or for the trailer? Wireless ones often do not have the range to work well from the back of a trailer.

For my truck.  It has an extended cab.  Worried about the range.

I bought a $60 wireless system via EBAY and mounted it on the rear of my 189R.  The reception was intermittent and I had to add a short length of coaxial cable and mount the cameras antenna on a rooftop vent pipe so that it could see the truck better.  Cameras are sometimes available in several view angles, choose the widest if you intend to use it as a backup camera and the narrowest for use as a rear view camera.
