I've hooked many a trailer up by myself - and yes, a BU cam would be helpful. But I wouldn't pay the extra coin for one, I dislike being forced to purchase this crap if I want a new vehicle, and most importantly, I don't want the damn screen in the middle of the dash! So I'll do it the old fashioned way. I've done it all my life, and I can continue to do it without mandated tech. Its bad enough that I have a GPS in all my vehicles - at least the screen is dedicated to that one function, it isn't ginormous, and its up high and out of the way, not in the middle of the dash taking up real estate that is better served with HVAC knobs. And it turns off when I'm not needing it as well.
