2010 Nissan Frontier truck - 26.7 mpg
 

new best for my truck. EPA is 20 mpg. no mods yet-only driving habits. want to put a homemade cap on and grill block/air dam this summer. thanks for all the tips.

That's really impressive. What truck engine and drivetrain configuration?

Was it mainly highway driving?

4.0 L, 6 speed automatic, 4 door, short bed.
Mostly highway, keepin it at 60 mph.
I think not having a bed cap or cover really hurts.
