With the high cost of replacing skins, or worse yet the upper curved end panels, I've got to ask, why doesn't someone invent or reinvent some kind of proximity warning system? I dinged the bumper of my 2005 22 ft CCD while backing up at night, which wouldn't have happened if I'd had something like a curb feeler. The hillbilly who put a small crease in my 25 FB SE ... well that's just bad luck, my choice was risk him hitting me or drive over the side of a mountain.
A backup camera is nice, but it's limited view. I'd like to hear a nice BBBBBEEEEEP! if I was backing too close to an overhanging limb, etc.
Comments? Suggestions? Inventions?
