Ford Explorer Mileage When Towing Trailer. I get about 9mpg when towing our startcraft travel trailer with or without the hypertech econ program, sucks but it beats getting a new vehicle to save $$ on gas. Heaviest i've towed was 4200 lbs for 7 miles and the explorer.
This number is a little. I tow regularly with a 2017, 3.5 naturally aspirated.
