MetroMPG -- a "quick & dirty" empirical equation for estimating MPG vs. MPH is:

MPG = CONSTANT / MPH

...where: CONSTANT = (40mph*mpg + 50mph*mpg + 60mph*mpg)/3

...which is basically: CONSTANT = MPG MPH...a constant "product" equation.

Pictures and scale weights lend insight. Guesstimates are hard to deal with for predictions among various trailers, loads, tow vehicles. The load in the tow vehicle "maybe" could have been moved to trailer and kept tow vehicle front end from rising.

FYI, added a photo to post #20 of the Ridgeline + trailer from my weekend 24 mpg expedition.

And once I got into town, I swapped the trailer over to a more efficient hauler...

Thats disappointing. I had a Tacoma that managed 18mpg no matter what I did to it short of FASing. Towing it got 16mpg. I had hoped unloaded and driven in an eco manner the Ridgeline was able to do at least 30mpg. Guess I will stick with my suzuki sidelkick ljx. He gets 32mpg.
