will it trace a single wire

I just tried it because I wasn't sure, you won't be able to trace the wire in the wall but you will be able to identify a single conductor when you touch the probe to the other end of it.

I need to trace a 12V wire through an RV to determine where it is shorted; is this device appropriate for this purpose?

If you can get to the wire or know where it is running it will work to trace where you are losing power RV walls are pretty thin

Can I use this kit to find a Cat-5 cable behind sheetrock, 2-3 inches at most ? If not, which product does this ?

Not sure. You might be able to if you can connect the tone generator to one end of the Cat5 cable. The signal would be very faint, at best, as this device is made for the probe to actually touch the wire. Not familiar with a tone generator that would work this way, but the Home Depot has a device that will allow you to see through walls to see what's behind it. Sound like that would be more what you need.

Will this test camera wires with rj45's at each end to confirm proper connections

If you just need to test for continuity then you can put an rj45 jack on each end and tone one end and test the other you can see if you have continuity
