It wouldn’t shock me if this were true, at least for steady state highway speeds. The differences in drag coefficient of the different size trucks would probably be dwarfed by the aerodynamic drag added by the trailer. Where I’d still expect some differences are in stop and go city traffic where weight differences of the vehicles could still have a noticeable effect on economy.
Yep, probaby right, but I'd imagine even that number is still down in the weeds as far as being better/worse.
I know if I slow down, below 65 or so my mileage shoots up to 12/13. Even better if I'm in the 55mph range.
Someone convince TFL to do a Ranger/F150/F250(Godzilla) MPG comparison. 3 Identical RV's Trailers all at the same time with highway/surface street mix.
