I was at autozone and saw a product designed to make it easier to line up the truck and trailer coupler, all it is is 2 tennis balls on long sticks! one goes on the truck and one on the trailer coupler, the idea is if you can see the 2 tennis balls, you can line it up on the first try everytime, but they are asking $28. for this product?! Couldnt anyone just make something like this with junk around the garage, doesnt have to be tennis balls either. They are likely making a killing on this though, Ive said it before, people will buy anything that is put in front of them! After awhile, anyone can usually line it up on the first try anyway, I now can do it too, and can get a feeling for where the ball is.
