Need some SLX7 174BH (non-Baja) measurements

[Plan-B]

Newbie 1st post here. My wife and I have settled on the 174BH floorplan and I'm making the plans to get the tow equipment up and ready. I'm going with the Andersen WD hitch, but I can't seem to find any good posts online with measurements. For anyone with a recent 174BH (we've got leads on a brand-new 2021), can you measure the coupler/tongue height when level and the frame thickness? Specifically, I need the numbers for the standard, non-Baja model.

Frame is rectangular 3" x 2". Bottom of ball coupler lip tip to ground is 21" when level. I like to tow with the nose slightly below level.
