I think I would rather spend the time learning how to back up without the computer!
our youngest DD is an equestrian, has two horse trailers, both GN, one about 20' two horse, I call it her Daily Driver. She uses it for hauling her horses to riding lessons. She whips that around like it isn't back there.
The other is a four horse with small living quarters a bit over 30', but axles located near the rear of the trailer, she does just as well with this one.
This is it when we were picking it up with the old 2001 Ram 2500.

My daughter can do the same with her GN horse trailer but as I said, big trailers are easy. A trailer like this would be a test on anyone's skills and that is where I think the assist would be most useful. And once you learn how to use the assist you might find it more comfortable in other applications.
