Coupler Height

[MandMCTexas]

Hi all. I will be picking up my new Eagle 330RSTS next weekend and will be ordering Blue Ox SwayPro since I didn’t like the one they were willing to include in the deal.
If anyone knows the height at the top of the coupler when the trailer is level for this model so I can get the initial height set up when it comes in, I would appreciate the help. I’ve seen a couple conflicting measurements that may be explained by tire size through internet searches. This one has the 16” wheels with Goodyear Endurance radials and underslung coupler.

Thanks.
