Here’s what happened when I tried to backup this rig :

I have successfully backed up this rig for 100 feet to unload the trailer. This is very tricky unless you are backing up straight; Once the accordian starts to squeeze, you can pull forward a few feet, then back up again. The photo above is a trip that I took with my wife from Denver to Sturgis bike week. I was paranoid that the bike was going to fall over even though I sinched up the straps as tight as I could. Oh how I wish I had a backup camera where I could monitor the status of my Harley Davidson FLHT on the back of the trailer.
Here’s what I did :
Purchased a backup camera system from Best Buy (on sale for $249.00) and brought it home. After unpacking the box, I realized that this is not an easy task : The kit actually included a new rear-view mirror with a little screen in the corner of it. The wiring requirements were extremely complicated, including a connection to the vehicles wiring harness so the video would display only when the truck was in reverse. ok… I packed that thing back into the box and headed to Best Buy for a refund.
Then it struck me : What about a webcam ? I could sit my laptop next to me in my truck and mount a camera on the back of the fifth wheel. The only trick was to get a very long USB “extension cord” so I could connect my laptop to the cam thirty feet behind me.

I bought an ethernet to USB converter for less than 10 bucks and I had some leftover CAT 5 ethernet cable from a few years back. I ran the ethernet cable from the back of the fifth wheel underneath all the way to the front of the fifth wheel (keeping the cat 5 concealed). Notice in the picture, you can see the wire running up to the back window of the fifth wheel. Then I simply ran the cable into the cab of my truck through the back window (window still shuts fine) and pluged directly into my laptop with a ethernet to USB converter.
I was able to keep a close eye on my bike all the way to Sturgis. The only thing I would suggest is to wrap your ethernet connections with electrical tape so the moisture can’t get in. My cam lost connection when it rained on the way back.
