In my towing I found a large increase in milage if I could hold 8th gear with my travel trailer. A very slight downhill or tail wind makes it easier. Also I found there is so much wind resistance at 65 with my trailer that it is easier for it to have the power it needs to maintain 8th around 57-58 mph. I do like tow mode though that the gears don't hunt as much and shift down going downhill and stopping
