Pulled yesterday ( 400miles) with my new to me 99 f250 sd. Pleased with the power but a bit disappointed with the fuel mileage (9.5 mpg ) when we stopped at 300 miles. Do I have an unrealistic expectation of 12 or better. I used to get 8mpg when I towed with a 07 Chrysler aspen hemi.99f250sd long bed 7.3 king cab. 2017 heartland pioneer bh300 dry weight 7000. Loaded 7700

The big difference now is your pulling a "wall" down the road.

If this particular trailer's "dry weight" is truly 7000 lbs I'd find it difficult to believe it weighs in at just 7700 lbs fully loaded and ready to camp. Regardless, 9.5 mpg pulling a barn door weighing almost 4 tons at highway speeds with an F250 seems reasonable to me. I typically see low 12s but I'm towing a 19 footer weighing well under 5000 lbs with my 1/2 ton Silverado - same barn door but a heck of a lot less weight, so expecting a 3/4 ton to achieve the same while towing so much more is IMO unrealistic.

How fast were you going on the highway?

Mileage sounds reasonable without knowing the speed you were traveling.Can't find your model listed anywhere..
