Re: Diesel fuel economy

My 2005 D max makes about 16 highway @75mph emp. My last trip towing just the DB it made 15ish running <65mph. Towning the SeaHawk(4500lb with gear and fuel) running 65mph I make about 12mpg. Load the camper on and tow a boat and its 10 or less depending on foot. These #'s are @ 4500' above sea level. I do better once I get west of the mountains. If I drop to 60mph I can add 1-2 mpg to the #s.
The one I hate is the camper&boat #'s. Most of my local trips run $100 in fuel not counting boat gas. Fuel $$$ putting a big hurt on my road trips.
