About the Trailer Hookup design

One wheel does all the work here, a thick ring with a round opening at its center, sitting low and left of the body so it hangs well below the floor line. The trailer above it is drawn as two stacked openings, the upper one split by a divider into a short left slot and a taller right square, with the roof bar running out past the front corner like a small awning. The floor line keeps going the other way and finishes in a broad arrowhead pointing right.
