I say with all my conviction GO FOR IT. We bought the Voyager system when we purchased our Airstream and had the dealership install it. My husband and I both feel that this was the smartest and best purchase we made. Parking is a snap with it (I always park and hubby guides a bit) and we love that we can see traffic behind us when driving on the highway or other. Another great feature is the voice transmission, so I can hear what is going on behind the trailer when it's plugged in. This was a great purchase and I know we paid about 400$ more, but then we had it installed by the dealer.
The trouble is, you think you have time. ~Buddha
