We bought our 2013 PC 2350 seven years ago this month from its original owner that had only used it eleven months. It was without blemish and we have loved it for seven years now. From the outset I was displeased with the factory installed backup camera. This "option" was about a $1,000 on the retail PC list for the vehicle. It was, to be honest, a sorry camera/display IMO concerning resolution and field of vision (yes, I tried to adjust it on numerous occasions) was not adequate. The screen was also smaller in the Sony compared to the new wireless display. In any event, I replaced it with this model:

I will report that the new wireless worked on a trip earlier this month without any jiggle or problem and the resolution and field of vision was excellent. I can't believe I waited this long to replace the Sony. By the way, the camera and transmitter are integral and one piece in this camera, unlike some wireless models where the camera transmission is from a separate device.
If you read the Amazon reviews you will find those that the camera performed well for those who were pulling fifth wheels as well as motor home users.
