That is fairly simple with some trigonometry.

The hypotenuse is the trailer tongue. The shorter end is the distance between the tongue and the first point of contact. The bumper is a known thickness. The bumper hitch is a known length, of which you need half. The pivot point is a known distance out from the bumper perimeter, which will effectively decrease the thickness of the bumper. What you need to know is part of the distance of the third side.

The main question is, at what angle will the tongue contact the bumper, and will the trailer's bumpers contact first at that angle?
