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.
Looks, solid reliability, bed extender, bedliner, ABS works terrific in the snow.
Power needs to be increased to at least 170 hp, get rid of the sliding rear window as it enables thieves to break-in, improve the brakes.
