Aging father has a mobility scooter carried on a hitch mounted carrier, on the back of his Expedition. His current rearview camera is obscured as a result. He wants another one to mount up high, possibly wireless(?) .Is this a good idea? Recommended model? Will this work and give a good view? I may not be able to help him, as I’m in Michigan, and he’s in Florida. Crazy Bel Air looking buggy for your time.
