The 2007 Dodge Ram HD comes in three trim levels, ST, SLT and Laramie, and three cabs (regular, Quad, Mega) with a range of engine choices, payloads and towing capacities. A TRX4 (mild off-road) and Power Wagon (more severe off-road) model are offered only on 2500-series trucks.
The Mega Cab 1500 is the light-duty configuration, but still has the heavy parts underneath and can haul payloads of up to 2,430 pounds and trailers of up to 8,750 pounds when equipped with 4.10:1 axle gears. The Mega Cab 1500 comes with the 5.7-liter Hemi V8 and a five-speed automatic transmission, and prices range from SLT 4x2 ($31,270) to the Laramie 4x4 ($40,725).
The 2500 ($25,905-$42,925) comes standard with the Hemi V8 with six-speed manual or available five-speed automatic, optional with the Cummins 6.7-liter Turbo Diesel ($7,095) and a six speed manual or six-speed automatic ($1,575). The Power Wagon is $37,035-$39,990 depending on cab, and 4WD adds about $3,000 to any standard 2500-series.
The 3500 ($30,515-$49,090) may appear pricey because the Cummins diesel is often standard equipment, especially on dual rear wheel models. Engine and transmissions are similar to 2500 models, though the Hemi doesn't rev as much and is detuned to 330 hp.
For adding your own box or work platform, Chassis Cab models are offered in regular and Quad cab versions of 2500 and 3500-series trucks, starting at $21,635.
ST models are workhorses, with standard vinyl floor and upholstery, although they do include chrome bumpers and grille outline, air conditioning, ABS, CD player, intermittent wipers, sliding sun visors, a full-size spare, and tinted glass. Options are limited to powertrain and chassis equipment, side curtain airbags, and a few cosmetic upgrades.
SLT, the standard trim on Mega Cabs, includes Essentials stain-repellent cloth upholstery, an overhead console with mini trip computer and compass, speed control, power windows and door locks, keyless entry, and power mirrors. Options for SLT include a power-sliding rear window, a bed liner, powered trailer tow mirrors, sun roof ($850), power adjustable pedals ($120), AM/FM/6CD/MP3 with Infinity speakers ($950), cassette ($100), navigation radio ($2,545), Sirius satellite radio ($195), DVD rear-seat entertainment system ($1,200), UConnect Bluetooth hands-free wireless communication system ($325), bucket seats ($490), and 17-inch forged aluminum wheels ($345). A part-time electric shift transfer case is available on 4WD models.
Laramie models add leather upholstery, dual-zone climate control, steering-wheel-mounted audio controls, heated front seats, security alarm, auto-dimming rearview mirror, and Sentry Key engine immobilizer. Options on the Laramie package include an entertainment system, sun roof, bucket seats, Bluetooth, and the navigation radio.
Safety features include dual front multi-stage airbags, three-point belts in all seating positions with constant-force retractors, LATCH child-seat anchors, child-protection rear door locks, and four-wheel anti-lock brakes. Side-curtain airbags for front and rear seats are optional ($490).
