Generally that makes sense, but design details vary. Among conventional WDH's, the round bar designs tend to hang lower than the trunnion designs.
More importantly, WD hardware clearance has nothing to do with the tow vehicle or its hitch receiver height.
- The trailer's coupler height determines the ball height,
- the ball height determines the height of the hitch head (or ball mount platform without WD),
- the size of the hitch head then determines how low the bottom of all the WD hardware hangs.
Whether you tow with a monster truck and a two-foot drop from receiver to ball, or a Ferrari with a one-foot rise from (obviously custom) receiver to ball, the clearance of the WD bars or chains and other hardware doesn't change. Of course, if the ball mount or WD shank itself is lower than the WD head, there could be a problem.
Also, a vehicle with a long rear overhang places all this hardware further back from the tug's rear axle, so when going through dips in the road (driveway entrances are usually worst) the bits are more likely to drag if the overhang is long.
