I finally had a chance to do a little light towing with the new truck. 1,000 mile round trip on US and state highways with 55-65 mph limits and rolling hills. On the way up 27.1 and 19.2 returning pulling a 2,000 boat, hand calculated. The dash readout was about 1 mpg higher. Around 30-40% better than my '17 5.0/6 speed F150. Very little down shifting on the return trip and never below 8th gear on the steepest grades. Very happy with the 3.0 choice.
