RV backup camera stuff

I bought a rear view camera, side view camera and monitors for each on Amazon. The whole set-up probably cost a fraction of what Furrion would charge. I found that all the different types of offerings on Amazon are basically the same, just the brand names are different. Yes, they are cheap, but is Furrion really any better? Hard to tell. Anyway, I installed the set and they work fine. If I have to replace a component every once in awhile I will put up with it. The Voyager components I replaced lasted 30 years. I doubt that the new ones will.
