small update:

Found a short bed are hard top tonneau cover for $125!! even if the guy can find the hardware I can put some bolts through it with some rubber spacers and camper tape to seal it off from the rain.

I drew up some sketches to where I had a 3 piece plywood unit that folded up between the fender wells and laid flat in case I use the bed but for $125 I may got for the hard cover. it looks like fiberglass and molded over the tailgate with a lock too.

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:

Excellent find on the cover. That's a good price if it's in good condition.

Only take the air dam as far down as the lowest hanging pieces of your undercarriage, but as far out to the sides as possible to cover the tires. Lower than that and the improvement gets negated by the increased area.

Besides that I've read stories that described improvement all the way down to the ground, but every time the dam scraped the road the driver would grit his teeth. There's a point beyond which the improvement in performance isn't worth the added discomfort.

Looking forward to seeing how this goes. Start a garage page for your truck and we'll all be able to follow along.

I agree with elhigh on the air dam. Raising the front probably created even more turbulence under the truck than before. Anything you can do to smooth out the airflow will help. You may want to consider making a belly pan as well as an air dam.

My buddies brother works at some sort of factory that makes big rubber belts lol. Once I get my truck back from the body shop Iíll take some measurements for a air dam.

Iím going to try the tonneau cover, Mirrors folded for about 2k miles in late Dec this year. Then hopefully within a week I can get a rough air dam that doesnít interfere with daily use.

Iíll see about adding a pic of the current set up now and then after each mod etc
