Is there such a thing as a guide/positioner that will place the trailer hitch/socket over the ball when I back my pickup to the trailer without feeling that thump that tells me I'm there and another dent in the license plate? It's a bit of a pain when I get close and then have to inch back,get out, take a look, inch it back,until the hitch is directly over the ball. Then I can crank it down onto the ball. Weight on the tounge is 175 lbs., boat/trailer 3700 lbs., so guiding by back muscle power is also a pain. There's gotta be an easier way!<br />Thanks for reading this far.<br />Bud
