HWY Fuel Milages Ideas

Im driving a ton of miles each month. My truck is 3 weeks old and i have 6500 miles on it. Any ideas to increase fuel milage would help. But, im not willing to affect my warranty. Dont get me wrong, I'm thrilled with this truck and its milage, but every little bit helps.

Does anyone know if vented tailgates would increase mpg over stock tailgates, if so by how much. Can you legally drive with tailgates down?

What about aftermarket air intake kits.

Im playing with different speeds loaded, and unloaded to find the optimal speed/mpg on the hwy.

Any other ideas would be greatly appreciated

Get a soft bed cover. I have the Extang Tri fold model. This will help some.

I agree with the soft bed cover. I have one on my F150 and it increased mileage about 1 MPG highway.

What tires did it come with? A good hard tire with a tight tread pattern can help milage some as well. And keep your tires aired up to the max. It doesn't help the ride and make it wander a bit, but it will reduce your contact pattern to the road and provide a slight increase in milage.

Thanks guys, I have 17" tires. I keep them at 80 psi which is the recommended pressure. I believe a bed cover would help. But i have to be in the bed often. Maybe a hard retractable cover would be better.

It'll take a long time to recoup the cost of a retractable hard cover vs. a soft cover. I have a Truxedo Low Pro, and it just latches down in the back and velcros the rest of the way around. Close to open and back closed again is probaly less than 30 seconds (on a slow day).
