Two bed lengths are available, a 6-foot, 3-inch standard bed and an 8-foot long-bed. Ordering the long bed adds 20 inches to the wheelbase. Long-bed Rams also get a bigger fuel tank, 35 gallons in place of the standard 26-gallon tank. Long beds add $300-$350 to the price.

Several engines are offered: Most popular is the 4.7-liter V8, a modern overhead-cam engine. The most powerful engine in the regular lineup is the 5.7-liter Hemi V8, which adds $795 to the price. A 3.7-liter V6 is available for those who want the lowest price and maximum economy, but only with two-wheel drive. At the other end of the scale, there's the rip-snortin' 8.3-liter V10 in the SRT-10 models rated 500 horsepower and 525 pound-feet of torque.

New for 2005 is a six-speed manual transmission as standard equipment with the 3.7-liter V6 and 4.7-liter V8.

ST is the base level. It comes standard with air conditioning, but is equipped with wind-up windows, manual door locks, and vinyl upholstery.

SLT adds $1,700-$3,200, depending on cab style and driveline. It comes standard with the 4.7-liter V8, and adds cloth upholstery, nicer interior trim, a leather-wrapped steering wheel, a host of convenience items, and wider tires.

Laramie is the top trim level, with leather seating surfaces, dual-zone air conditioning, a premium stereo, 17-inch cast aluminum wheels, and a long list of luxury features. Offered in two packages, Laramie retails for $7,800-$8,900 more than the base trim level.

Sport trim, available for most models, includes fog lights, 17-inch aluminum wheels, body-colored exterior trim, and special interior trim. Aggressive 20-inch wheels and tires are also available.

The SRT-10 is available in both regular cab ($45,000) and Quad Cab ($50,000) models for 2005.

A power sunroof with one-touch open and close features is a new option for 2005 Quad Cab models. Sirius Satellite Radio is available for 2005 Quad Cabs as well. A new UConnect hands-free cellular telephone system that can communicate with Bluetooth-enabled cell phones is available, and there's a new integrated radio/navigation system.

The Off-Road package ($870-$1,405) comes with unique 17-inch aluminum wheels on LT275/70R17 off-road tires, 3.92 rear axle, limited-slip differential, skid plates for the transfer case and front suspension, special shocks, tow hooks, fog lamps, and a heavy-duty cooling system.

The Work Special package is designed to deliver affordability with gray bumpers, grille, and 17x7 steel wheels.
