Haha! he dragged me over here from FTE.....

For what its worth, I'm able to get 19 MPG towing a 20' flatbed trailer with 16" walls if I can keep it at 55 MPH. Same speed empty nets me 24 MPG.

With 3.08 gears and the transmission in overdrive, that puts me at 1200 RPM roughly. I will eventually retest those conditions in 3rd gear to see if the fuel economy is better or worse but the engine seems content to run at those low RPMs as long as the loading doesn't cause smoke lugging.
