Strange noise while upshifting - differential?

[Airstreampuller]

I have a strange kind of whop whop sound when my 2021 EB 4x4 10 speed up shifts to 7th gear at about 45 mph going up hill (when I get on it just a bit). It seems to be from the drivers side rear. It is very subtle and the dealer cannot recreate it. It is worse when I tow my travel trailer (7600#). Sometimes it occurs at other speeds and gear changes. It almost feels like a tire skipping (they are also wearing pretty fast). I am wondering it the locking diff could be dragging sometimes. Does this sound familiar to anyone? Thanks,
