Our Silverback 29IK came with the Furrion back-up system which was OK at best. I just replaced it with the Furrion Observation system which IMHO is far superior. I can now actually see the goofs behind me that are so close that I can't see them in the outside mirrors. I bought the new one from Amazon and as has been said before it was about $50 cheaper to buy the one with the mounting bracket than the one without. Go figure. I now have an extra mount although I can't imagine how the existing mount could fail. It took longer to get the ladder out than it did to swap out the units.
Some manufacturers wire the camera to the back-up lights and some to the running lights. Running lights allow you to use it any time you are hooked up.
I'm really happy with the new unit so far.
Cheers
