Around 8 or 9 MPG on flat and no head wind

Around 7 MPG when pulling a loaded 14’ enclosed trailer on flat ground and no head wind.

Going up pretty much any mountain pass in the PNW, you are better off not looking at the MPG readout as seeing the MPG drop to 3 or 4 causes a severe pain in your wallet.
