In town, which includes some freeway driving, I average 15-17 MPG. Towing my 5th wheel, I average 11.5-12.5 MPG, depending on the amount of Interstate on my route and number of mountain passes I have to cross.
If you are regularity getting 22.7 MPG in any 6.7 diesel you are very far out of the norm. You either have a very special, almost one of a kind, truck, or you drive very conservatively.
If it is the former, I’d keep that truck for a long time. If it the latter, you would likely get 35-40 mpg in a 3.0 diesel.
When I tow on the Interstate, I set the cruise control for 65 MPH because that's what my trailer tires are rated at. Those are OEM tires with 26,000 miles on them and I have never had a flat or blowout on this trailer. When I am not towing, I set the cruise control for whatever the speed limit is on the Interstate because because my last speeding ticket cost me $370 plus a court appearance. And I don't like going to court!
