BTW: Jacking the truck up 5 inches it retarded, it makes the frontal area increase tremendously, and screws up handling a lot.

Tires tires tires. A train weighs a lot but has a small contact area so resistance is relatively low. We all know those big fat tires lower mileage but Im not sure everyone knows why. I took off the softer mud tire and went to a much higher presser street tire.
When I was a kid I rode bicycles a lot. I started to get arthritis in my hands from riding dirt bikes so much I had to stop riding dirt. When I switched from a dirt tire to a high pressure street tire the difference was night and day. The street tire had so much less resistance. The hypermillers are overinflating to lower resistance even more.
Remove all unnecessary weight from your vehicle(even if it means your going on a diet). Racers know 100 lbs cost you a tenth in the quarter mile because
your wasting hp to get motivate the extra weight. I took a peek around my car and tire pressure is good and only about 20lbs extra weight in the trunk.
