The GL has a fairly long rear overhang, so the trailer hitch has significant leverage on the rear axle (lifting weight off the front axle)

I have no idea how you adjusted (or misadjusted) the WDH, but would like to know what you felt when driving that seemed 'wrong'.

A WDH absolutely transfers the load. Specifically, it takes weight off the rear axle and distributes them to the front and trailer axles. Technically it does not lower the tongue weight, though it does change the forces involved.

Euro SUVs have fairly short overhangs as compared to American SUVs and trucks. Exception being the Durango and Grand Cherokee (2011 generation) as they were based on the W166 and X166 frames.

Thanks!

Factory harness will plug into the rear SAM; there should be an open connection for it. You will need to reprogram the rear SAM and central gateway for trailer recognition and operation of trailer lights.
