Interesting mpg last trip
So... My "new" truck is a 2021 F150 with the 2.7 twin turbo and 10 speed trans. In general, this truck tows impressively better than what I had, a 2008 F250 Super Duty with 5.4 and 5 spd torque shift...

Below 60 cancels much of the aero penalty. The reason for the 55 in 1974 was that its Rolling Resistance to 45-MPH, and Aero Resistance after 60. 55 is a sweet spot.
The real test is against the TV loaded the same way on the same road at tbe same speed, but without the TT. The percentage change. If you can keep it to 40% that’s spot-on for 60-MPH whether 1973 or 2023.
As tow miles are a fraction of annual miles, the DD numbers are what matter. And where to learn to maximize MPG against the vacation travel. Where the savings are ACTUALLY located.
15.0-MPG is the exact middle of my range when at 60.
Highest highway efficiency will come to a truly aerodynamic trailer, first, and a turbocharged diesel (car or truck), second. There are those with 2006-era Mercedes TD sedans pulling 23’-25’ Airstream hitting low 20’s.
Spec the TV for its DD duties. Pulling a trailer ain’t the job many think it is as they’ve only ever driven around in empty or near-empty vehicles.
The average American runs 15k annually. How much does his average annual fuel burn increase (percentage) as a result of the average RV’ers 5k vacation miles?
It ain’t that much.
Gas DI T/C with 10-Auto? It’s not about the engine so much as it’s the software that keeps temps under control when a load introduced. VVT turbo and Auto-12 in big trucks same way. Computer is in charge.
Cut the aero load, and use CC 100%. No lane-changes or significant braking events. Find THAT sweet spot due to conditions (mainly traffic volume) to cruise above 60 (cancel CC and drop down to get slow passes over; law).
Never join a pack. Or allow one to form around you. Ever. Maintain maximum distance all day (gets easy with practice).
The latest big truck driving as above? These days he’s above 9-MPG with no adverse conditions while grossing 78k.
