Seems very familiar.....
Along with.... ok, right there, now three feet to the left...sigh... as I put the truck back in 'D'.
With us, my wife is my preferred person to be directing me when backing the trailer. After years of doing it we have it down pretty well. WE also have the soon to be gone Furrion backup camera with a mic. I am replacing it with a Christmas present of a New wireless camera system, but without a microphone. A friend has one and the picture is better than my Furrion. THat means Walkie talkies for us, or the phones. As stated earlier, I can hear the phone through my hearing aids, but a lot of places we camp have no service (the grand kids hate that - we love it).
