I have a 5 speed & 4:10's and running 40 miles back & forth to work, 65 mph hwy, plus a little city, I'll average 16.5-16.9 mpg. I just can't break that 17 nut. But pulling my 5th whl. drops me to 12.5. Even my 14' utility (quad) trailer will drop it to 15 mpg.
That's on dino fuel, I haven't...
Anyone know of a larger tank that would fit in place of the rear stock 18 gal. on a '96 F350, CC, lwb, PSD ? I would love some extra weight on the back end, plus longer cruise distance.
