2006 Nissan Frontier Crew Cab Nismo 4dr Crew Cab 4WD SB (4.0L 6cyl 5A)
Best "Mid-Size" Truck
 I traded a 2003 Ford Ranger FX4 Level II for my 2006 NISMO Crew Cab 4x4.  The Ranger was a decent truck but it got horrid gas mileage (avg about 14 with 80/20 city/highway).  I love my NISMO so much more than the Ranger.  It's a little bigger but it's more powerful, has a better ride, and handles way smoother.  It also feels much more solid than the Ranger.  I have to watch my driving because the truck wants to go fast!  I can definitely feel sports car roots in the truck.  The engine is smooth and refined and well matched to the 5- speed automatic.  Fuel economy is around 16 in town and I get a solid 20 on the highway.  The truck is a pleasure to drive.
