I replaced the differential oil, (it was over 11 years old).

It was taking about 140 amps to maintain 70 MPH, now it takes less then 100 amps to maintain 70 MPH. :)

So, if you have old oil in your differential, you might want to change it. ;)

I want to see if I am in the ball park, or do I have dragging brakes, bad wheel barrings, etc...

You're right in center field. On level ground I can actually maintain 70 using the Econ mode. I use Normal to get up to speed and as long as the road is level then 80 amps or less is all it takes to keep the speed up.

On Econ setting can go about 65-67 MPH on level ground.

If I draft a semi going 70 MPH I can maintain 70 MPH on Econ setting. :)

I am going to add 5 PSI to each of my tires and see if I get any better results. Currently I am just running 35 PSI in them.

Also, I sent an e-mail to the Areo department at work (they have 12 people), and they all had ways to improve the areodynamics of the truck.

I might try some of them, well, the non-crazy ideas. ;)

The easiest one was just to cover the bottom of the truck with sheet aluminum...

I read about a guy in texas that aero'd his small pickup out and increased his mileage to over 40mpg or some high number like that. He put a smooth sheet under it, and covered the rear wheel wells and then put a cover over the bed that went from the top of the cab and angled back to the level of the tail gate. I think he also closed off the grill and used some kind of ram air intake for the cooling rather than having the whole grill opened up. I think he also lowered the truck a little as well. None of these were very expensive and they all added up. He said the greatest increases came from a sheet under the truck and the angled bed cover.

I've often considered the sheet under the truck but have avoided the bed cover because I use my truck bed and I like my visibility, too.

A friend of mine is a NASCAR racer and he saw my truck and has told me I need to close the holes in the grille and I am using a tonneau cover rather than a topper . Wolf , I would be interested what your friends have to say we can do if you would not mind posting them.
