I chose this model as it could be converted to also use CNG and now I get about 20 mpg (CNG) on the freeway at 65 - 70 mph. With gasoline it would be 3 mpg better but CNG is $1.53/gal I use it in the mountains (+9000 feet) and it just goes anywhere. Upgraded to 285/75/16 tires for a snowplow (clearance) - Plow works fine with the 160 amp alternator. Replaced the catalytic converter in first year but otherwise no problems and I now have 34K miles and 2 years on it. I enjoy driving this truck. Its comfortable and rides easy. I tow a 8000 lb back hoe trailer with ease.
6 speed transmission with the manual gear selection option. 4WD on the fly shift in to or out of 4HI.
A 4WD indicator light on speedometer - the 4wd control is hidden by the steering wheel and gear shift. Larger tires.
