The 2010 Ram Heavy Duty isn't technically all-new, but it looks and acts the part. New sheetmetal, a new interior (both heavily derived from the new Ram 1500) and re-tuned underpinnings combine in a more stylish, more refined, more capable offensive lineman of a pickup. Also worth noting is that the trucks have earned their own brand, so now the Dodge Ram is just the Ram.
A new, more-upscale SXT slots above the entry-level SL on Regular and Quad Cabs and becomes the new entry-level Mega Cab model. Top-of-the-line Laramie-trim Quad Cab models add wood-like interior accents, all 2500s get standard trailering mirrors and the transition from high to low range on 4x4 SLT and Laramie models is now done electrically rather than via a manual lever, as it is on SL and SXT models.
The 2010 Ram Heavy Duty is the best heavy-duty pickup ever. For now, anyway. Dodge is first out of the gate, but Ford and Chevy are prepping new versions of their own workhorses, to be unleashed in 2010, and then it'll again be a level playing field. Until then, Ram HD gets to play undisputed king in an important segment, as heavy-duty pickups account for about a third of the massive full-size truck market.
