2004 Nissan Frontier King Cab 2dr King Cab XE Rwd SB (2.4L 4cyl 5M)
Solid Reliable and a great value
 I've owned my '04 for 4 years now.  Just got done with a 1500 mile trip to Lake Tahoe and not a single problem, fuel economy average was 26.95 mpg!!!  It's true that it lacks power but just use the lower gears and you will be just fine! I have towed 2000 lbs regularly without issues.   As far as reliability goes, it is GOLD, I haven't had a single problem so far.  In the last 4 years and 55,000 miles I only had a flat tire once!!  For the money you can't get anything better in the entry level compact truck segment.
