What type of system did you mount and what type did your friend mount? Also what was the estimated cost of both systems. My friend is pretty handy so it will definitely be a do it yourself project.
mastercraft> I still have that system in a box at home, unfortunately I am on the road for the next couple months and don't have access to it in order to give you the details. My friend paid about $550 for his B&W wired system 4 years ago. My wireless system was mounted on a 5W that I previously owned three years ago. (I now drive a motorhome). That system cost me about $200, but at the time, I was a dealer in RV electronics and got wholesale prices. However, I have recently seen prices for wireless B&W systems for as little as $99. Color or B&W doesn't make much difference in camera prices, but if you go with color then I feel confident that the most expensive part of the system will be a nice 5 inch color flat screen monitor.
I'd suggest that you do an online search for companies that sell wireless cameras and monitors. A few things to look for: 1- Longest transmission range possible. 2- 12V system 3- transmitter and camera combined in one package 4- monitor and with built in receiver. If that is to costly for him, then find a receiver to go with the monitor that is small. 5- The higher the frequency the better. The cheaper systems will transmit on 2.4 ghz, but the better ones that will best penetrate obstacles will have a higher frequency.
Once the system is selected, this is truly a DIY project. It only takes knowing how to hook up a red and white wire to the proper 12V source.
