rruff, was that 30 mpg on the truck's computer or scan gauge? or did you hand calculate at the pump at the bottom of the hill?
I have been on that road too, I can kinda see it if it was coasting in neutral.
What is the mileage coming back up?
Yes it has gotten stupid, but the last Fords we owned were trucks from the 70's and 80's. You would be hard pressed to get 100K out of them, they were pretty much done at that point. had 3 engines in our '76 F250 before 100K...though we did work the crap out of that truck, it had , ladder rack, bedside tool boxes and pulled a Bobcat skid-steer. That particular truck's frame rusted in half. Through its' life it had two beds, floor board and body mount rust repair, and 3 paint jobs. I got rid of it in 1991, which at that point it was only 15 years old.
What is crazy is that the current F150 would put that truck to shame, in towing, payload, power and efficiency.
I was the first to stray from domestics in my family to Toyotas...and got razzed to no end. Fairly loyal to Toyota, however all of the new trucks seem pretty good anymore...compared to the barbaric trucks of the 70's.
