Coupler height on 2022 320S Boondock

HardFault

Hello folks, 

Anyone know the coupler height for the 2022 320S Boondock? More specifically, what is the top-of-the-ball height required by the tow vehicle.

Thanks!

I have a 2023 320s Boondock here are my numbers, the top of the receiver tongue is 16.5 inches off the ground, the top of the ball is exactly 19 inches. When I connect my trailer my truck suspension sags about 1/2 inch. This gives me a level trailer while towing.

Thanks @TourDeForth, that's helpful.

The top of my ball is 18". I've not been able to test the impact of the 320S tongue with on my suspension yet, nor an I able to accurately assess the interior height of my coupler socket, but I'm starting to think 18" might be on the low side.
