400 Boondock Lite hitch height?

I measure 16" on my 400 boondock.  I use a 8" drop hitch on my Ram 2500.

I am trying to confirm this myself, NuCamp is telling my dealer 20" (he doesn't have any on the lot to measure), HOWEVER that is what NuCamp brochure says for a regular 400, the 23" shown above seems more likely correct for the 400 BD lite as there is allegedly 2.25" of additional ground clearance. Any other input appreciated! The height I am looking for is ground to top of ball required to make the 400 BD level when attached, realizing of course that may vary due to suspensions and loading. I need to get a new ball mount prior to picking up my 400 BD.

@BigGrover, thank you! I was thinking a target of 22" to top of ball might be about right, going to need a new stinger for the 400! I have a 6" drop right now, but that puts the top of ball about 18.5" above ground, so I need to come up at least a couple inches. I would rather have trailer hitch down an inch or so vs being high. One more question, do you know the width of the coupler latch? Trying to figure out what span of latch lock I need while towing? Obviously a Proven Industries might be good while unhooked, BUT I always put a locking pin on the coupler while attached to tow vehicle.

@BigGrover I thought about getting the adjustable, BUT with only two trailers it seems cheaper to grab a new one for around $50 for the 400 and just keep each with the respective trailer.
