Well, wife heard me yammering about fuel economy and the truck. She ordered me a tri fold soft tonneau cover lol. Seems it would be a good mix for covering items in the bed, yet semi rigid for the hopefully improved economy.

I leave in late December and I have the recording from last trip only a month earlier the prior year. So if I’m hitting 18-19 mpg I’ll know there was an improvement.

16.7- running 80hp time 65-68mph average.
17.7 running stock ecm file stopped at same gas stations on the way back.
Little over 2k miles round trip. Drastic elevation changes, big up/down hills but again if a tonneau helps me I’ll know at the pumps.

Here is the link to what she ordered me:
1999 f250 4x4 7.3l automatic
19.5 mpg freeway- Newbie looking to improve!
-Tonneau cover, Intake, Straight pipe, improved turbo compressor wheel.
