2019 RAM 2500/3500 Mega Cab II (DT) Dimensions, Size & Specs

With the side mirrors extended, the RAM 2500/3500 Mega Cab II measures up to 2,450 mm (96.5 inches) wide. This considerable width is essential for maximizing visibility, especially when towing large trailers or hauling wide loads. However, this expanded width can pose challenges in urban environments, narrow streets, or tight parking spaces, requiring cautious maneuvering. Drivers often need to fold the mirrors where possible or take care when navigating narrow lanes, as the wide mirror span exceeds many standard vehicle widths, potentially complicating parking and passing through constricted areas.

The RAM 2500/3500 Mega Cab II carries a curb weight between 3,191 kg and 3,891 kg (7,037 to 8,581 lbs), reflecting its robust construction and heavy-duty capabilities. This substantial weight contributes to a solid and stable feel on the road but can affect fuel efficiency, with larger engines required to provide adequate power and towing capacity. Heavier weight also influences handling dynamics, typically making the vehicle less nimble than lighter pickups or SUVs, but improving towing stability and load-carrying capacity. Owners should balance these factors depending on their usage needs, from daily driving to demanding work tasks.

The maximum weight, or Gross Vehicle Weight Rating (GVWR), for the RAM 2500/3500 Mega Cab II ranges between 4,536 kg and 6,350 kg (10,000 to 14,000 lbs). This rating indicates the maximum permissible total weight of the vehicle including passengers, cargo, and trailer tongue weight. High GVWRs reveal the truck’s strong capability to safely carry heavy loads and tow substantial trailers, positioning it as a top-tier heavy-duty pickup fit for demanding commercial, agricultural, or recreational towing duties. Operators should always ensure that combined loads do not exceed this rating to maintain safety and vehicle longevity.

With the rear seats folded, the RAM 2500/3500 Mega Cab II offers a luggage capacity of approximately 1,628 liters (57.5 cubic feet). This expanded interior hauling space suits those who require extra covered storage that is protected from weather rather than just an open bed. This capacity is particularly useful for transporting tools, equipment, or oversized items securely inside the Mega Cab’s spacious cabin, complementing the vehicle’s heavy-duty exterior cargo bed capabilities. It offers a blend of comfort and utility, ideal for both work and leisure purposes.

The RAM 2500/3500 Mega Cab II boasts a ground clearance of 334 mm (13.1 inches), which is relatively high for a pickup truck. This elevated ride height aids significantly in off-road performance by allowing the vehicle to clear obstacles like rocks, uneven terrain, and debris without damaging the underside. The generous ground clearance also enhances water fording capacity and overall off-road capability, making it suitable for rugged environments. Combined with heavy-duty suspension components common in this truck class, it is well-equipped for off-road adventures or demanding job sites.

The RAM 2500/3500 Mega Cab II comes equipped with various rim sizes including 8.0J x 18, 8J x 20, 6J x 17 and options spanning from 17 to 20 inches in diameter. Tire sizes compatible with these rims include 275/70 R18 E, 285/60 R20 E, and 235/80 R17, all of which are heavy-duty tires designed to withstand substantial loads and off-road conditions. Large rims combined with suitable tires contribute to improved road grip, stability under load, and ride comfort. The tire's robust design supports heavy payloads and towing, balancing comfort with durability and performance both on highway and rough terrain.

Given the RAM 2500/3500 Mega Cab II's length of 6,348 mm (249.9 inches), height approaching 2,036 mm (80.1 inches), and width up to 2,450 mm (96.5 inches) with mirrors open, fitting into a typical residential garage can be challenging. Standard single-car garages usually measure about 6,000 mm (20 feet) in length and 2,400 mm (8 feet) wide internally, which means the truck’s length slightly exceeds this and width may be tight even with mirrors retracted. Owners planning to park this heavy-duty truck in a residential garage should verify their garage dimensions and may require larger or customized garage spaces to accommodate its size comfortably.

Compared to its predecessor, the RAM 2500/3500 Mega Cab II generation (starting in 2019) maintained a similar overall large and commanding footprint but offers modest increases in certain dimensions like length and width to improve cabin space and utility. The Mega Cab layout emphasizes enhanced interior room over previous generations, leading to more passenger comfort and cargo volume inside the cab. While both generations sustain a heavy-duty presence with substantial GVWR and ground clearance, the newer Mega Cab II incorporates modern design cues and engineering refinements that optimize its size for both urban usability and rugged utility without drastically altering its traditional full-size pickup proportions.

In comparison to similar heavy-duty pickups like the Ford F-250/F-350 Super Duty and Chevrolet Silverado 2500HD/3500HD, the RAM 2500/3500 Mega Cab II stands out for its spacious Mega Cab layout, which generally offers more interior passenger room than many competitors. Dimension-wise, the RAM is similar in length and height to its rivals but can be slightly wider with mirrors extended, emphasizing towing visibility. Its ground clearance and GVWR are competitive, placing it firmly in the top tier for heavy payload and towing. The RAM’s balance of interior spaciousness, strong size, and capability makes it an attractive option for those who prioritize both comfort and work-truck utility in this segment.
