Assuming you want the 5k-6K tow rating for overkill (I see you have a B19, 2900 lbs dry), you could consider Toyota Highlander (my '08 was very reliable and did 140k miles of towing for me).
Durango has been mentioned, and their 3.6L does seem to get relatively good gas mileage, but parts availability from FCA would have me concerned.
The Subaru Ascent (new for 2019) could work.
Chevy Traverse/GMC Acadia is another to look at.
Honda Pilot has 3 row seating.
So does Nissan Pathfinder, and my mechanic thinks they may have finally gotten their act together and solved their CVT issues.
In terms of long term quality and reliability, I favor the Highlander and Pilot, with the Subaru maybe coming in at 3rd place.
