I got 2+ years good use ou of a Furrion FOS48 observation system which was $300 or so at Amazon then the lens/camera went bad.
Called Furrion wanting to buy just the camera. Not available. Model is discontinued despite still being offered at Amazon and other vendors.
They suggested I buy their new model complete , the "vision" system, for $500.00 and it appears to use the same camera that failed which is not available.
Take your chances with Furrion. They partnered with LCI a few years back and now use the LCI non available or inflated price parts tactics.
