Both good suggestions. I do have a USB charger already, just put some Velcro on the door to mount it. And most of the places we are likely to be going to would have good cell service.
I’m actually not that bad at backing the trailer if I take my time and have a good spotter, but last night was a good example of how a camera would be handy. I was by myself, backing a trailer full of our band equipment into a space between the pavilion we were playing in and a playground . Because of all the little kids running around, I’d back a foot or two, stop, get out and walk around back to make sure it was clear; repeated that about a half dozen times before getting to where we wanted it. I’d still go slow and check a few times, but it would be better at least having some clue as to what is going on back there.
Too bad there isn’t a sub-app that would allow directly reading the cam data if on the same network.
Thanky kindly again folks, spot on comments.
