We Recommend

Big Horn trim will be perfect for you which not only offers all the cab styles. It also lets you have a great driving experience with a punchy engine along with all fundamental features at a low price. You can also go with the Big Horn Silver Edition which RAM will introduce for the 2022 model year. 

2022 RAM 3500 Mega Cab Diesel Release Date

RAM has published no official announcement about the release date of the 2022 RAM 3500 Mega Cab diesel.

2022 RAM 3500 diesel Mega Cab Engine and Performance

9.0/10

The 2022 RAM 3500 Mega Cab has a standard 6.4-liter gas V8 power plant which is married to an 8-speed automatic transmission. It churns out 410 hp and 429 lb-ft. However, you can always swap it with the 6.7-liter Cummins Turbo Diesel Inline-6 which is mated to a 6-speed automatic transmission and generates 370 hp and 850 lb-ft. That said, all trims are available only in the 4X4 drivetrain configurations.

You can also select the optional high-output version of the 6.7-liter diesel engine which puts out 420 hp and 1,075 lb-ft. The payload capacity with the low output diesel engine is 4,300 lb which is 40 lb less than with the gas engine and 160 lb more than the high output diesel engine. The towing capacity, if a gas engine is equipped, is 19830 with a 3.73 axle ratio but 19,830 lb when the low output diesel motor is selected. That said, the punchy version of the diesel engine gives a towing capacity of 24,080 lb, thanks to its higher torque outputs.

The RAM 3500 Mega Cab has the least engine output in the competition while the highest output is given by the 6.7L Power Stroke V8 Turbo of the Ford F-350 crew can which generates an additional 105 hp and 200 lb-ft of torque. The payload capacity of the Ford counterpart is 4260 lb at 11,300 lb of GVWR, unlike other cabs whose GVWR is in the range of 12000. Ford F-350 shares the towing capacity with the opponents from the Chevrolet and GMC which have a lower payload capacity than the RAM but a slightly higher towing capacity.

2022 RAM 3500 diesel Mega Cab Fuel Economy

9.0/10

There will be no EPA data on the fuel economy for the 2022 RAM 3500 Mega Cab diesel since EPA does not measure the fuel efficiency/economy of the heavy-duty trucks. That aside, the 3500 Mega Cab diesel is equipped with a fuel tank capacity of 31 gallons which is 3 gallons more than the regular cab diesel variant. But the RAM 3500 Mega Cab has the smallest fuel tank in the segment.

Just like RAM 3500 Mega Cab, there are no official fuel economy figures for the competitors. Be that as it may, the biggest fuel tank of 36-gallons is extended on the Chevrolet 3500HD Crew Cab Diesel and GMC Sierra 3500HD Crew Cab Diesel. The Ford F-350 Super Duty Crew Cab can store two gallons less fuel compared to the counterparts from the previous counterparts. 

2022 RAM 3500 diesel Mega Cab Interior

8.0/10

The RAM 3500 Mega Cab offers a class-leading interior. The cabin is smaller than the competitors but the quality of the materials inside and comfort has not been compromised. Cloth upholstery is standard on the Big Horn but it can be upgraded to Premium Cloth or leather. The Mega Cab variant of the RAM 3500 has a 40/60 pattern rear bench seats and front seats with the 40/20/40 pattern.

That said, the heated rear seats, front and rear ventilated seats are reserved for the higher trims.

4-way manual adjustment is standard and 8-way power adjustment with 2-way power lumbar support is optional. The RAM 3500 Mega Cab has a steering column with only a tilting feature while the rival also gets the telescopic feature. Manual air conditioning, Speed-Sensitive Power-Locks, Remote keyless entry, power windows, 12V power outlet, and day and night rear-view mirror are some standard features while the Dual Glove Boxes, auto-dimming rearview mirror, Rear Window Defroster, Digital Rearview Mirror, 115V power outlet, Power Adjustable Pedals, and door trim panel foam bottle insert are available to cabin features.

Though the interior space of the RAM 3500 Mega Cab is not disappointing, fellow opponents offered a much better cabin in terms of space at least. The Chevrolet 3500HD crew cab and GMC Sierra 3500HD Crew Cab have the best front headroom and shoulder room and also get the best cargo capacity of 69.5 cubic feet, but the Ford F-350 Super Duty crew cab has the most generous dimensions in the second row. That being said, as far as luxury and comfort are concerned, rivals have no choice but to yield against the RAM. Highlights of the interior features are:

  • Cloth upholstery 
  • Hydrographic metal patina finish
  • Heated front seats 
  • Rear power-sliding window
  • Dual-Zone Automatic Temperature Control
  • Heated Leather-wrapped steering wheel
  • LED ambient interior lighting
  • Remote Keyless Entry
  • Power door locks
  • Auto-dimming rearview mirror
  • Universal garage door opener 

How intuitive is the 2022 RAM 3500 Mega Cab diesel’s infotainment unit?

The new 2022 RAM 3500 Mega Cab diesel will have a new Uconnect 5 system which is faster than the previous generation of the infotainment system and comes with Wi-Fi capability, tow-specific navigation, and will bring on-air updates in the future for better performance, new features plus services. The base trim comes with a 5-inch touchscreen which can be upgraded to an 8.4-inch touchscreen with navigation or a 12-inch touchscreen on the higher trims. 

A 6-speaker sound system is standard that can be traded with the Premium 7-Speaker System on the Big Horn and 9-Alpine speakers sound system with the subwoofer on trims beyond. A 17 Speaker Harman Kardon premium sound is only available on the top two trims. Bluetooth, USB port, aux jack, 7.0" TFT Color Display, and active noise cancellation are some standard infotainment features. Highlights of the infotainment features are:

  • 5-inch touchscreen

  • 6-speaker sound system 
  • HD radio (optional)
  • Premium 7-Speaker System with an amplifier

2022 RAM 3500 diesel Mega Cab Exterior

8.0/10

The exterior design of the RAM 3500 Mega Cab is nothing anyone can just scoff about. For 2022, RAM has given a unique grille design and texture on the Big Horn trim. The RAM 3500 Mega Cab has an aggressive grille with halogen headlights on the Big Horn trim which can be upgraded to LED headlights on the higher trims. 18-inch chrome-clad steel wheels are standard on the Big Horn but can be replaced with the 17-inch wheels, or 20-Inch black painted alum wheels. LED taillights, headlights, power-folding side mirrors, and fog lights are optional on the entry-level Mega Cab but incandescent taillamps, winter front grille-cover by Mopar, rain-sensitive windshield wipers, acoustic front door, and window glass, tinted acoustic windshield glass, and heated side mirrors are standard.

The Crew Cab is offered in both short and long-bed configurations and the crew cab can be considered Mega Cab’s rival as both cabs have minor differences if a short bed is selected on the former. That said, the biggest cab in the competition is from the GMC which shares all exterior dimensions with its mirror image from the Chevrolet. The largest wheelbase of 160.5 inches is present on the RAM 3500 but the highest ground clearance of 11.2 is provided on the GM twins. On the other hand, the Ford F-350 SuperDuty Diesel also has similar dimensions as its competitors and is the lightest truck on offer weighing 7,379 lbs. Highlights of the exterior features are:

  • Unique grille
  • 18-inch chrome-clad steel wheels 
  • LED headlights and taillights 
  • LED fog lights
  • Chrome front and rear bumpers
  • Rain-sensitive windscreen wipers

2022 RAM 3500 diesel Mega Cab Safety

7.0/10

The National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) have not evaluated the 2021 RAM 3500. That being said, cruise control, rearview camera, anti-theft system, hill descent control, hill start assist, front and rear park-assist system, and trailer sway damping are some standard safety features given on the RAM 3500. For 2022, with the trailer 360-view cameras, the driver can get a 360-degree view of the trailer exclusively which will deliver better visibility of the trailer surroundings. 

Optional safety features are given under Safety Group B ($2,620). This package is applicable on the Big Horn and Laramie and adds adaptive cruise control with stop, lane keeps assist, full-speed forward collision warning plus, and adaptive steering system. The Safety Group ($1,590) is a package only offered on the top two tier trims and adds the same features as the previous group. Highlights of the safety features are:

  • Cruise control
  • Trailer sway damping 
  • Adaptive cruise control
  • Surround-view camera system
  •  Lane Keep Assist
  • Front and rear parking sensors 
  • Blind-spot monitoring 
  • Rear cross-path detection

2022 RAM 3500 diesel Mega Cab Competition

9.0/10

RAM 3500 Mega Cab Diesel vs Chevrolet Silverado 3500HD Crew Cab Diesel SB

Against RAM 3500 Mega Cab, the interior and exterior of the Chevrolet 3500HD Crew Cab are basically bland. Additionally, the infotainment system offered in the RAM is much better compared to this Chevrolet counterpart. It is true that the Chevrolet 3500HD crew cab can tow 30 pounds more than the RAM 3500 Mega Cab and has better power figures in comparison but in terms of comfort and ride quality. However, Chevrolet has given a more cargo bed volume in the Silverado 3500HD. 

RAM 3500 Mega Cab Diesel vs GMC Sierra 3500HD Crew Cab Diesel SB

Anyone who has an interest in trucks is familiar that the GMC Sierra 3500HD and Chevrolet Silverado 3500HD are twins as far as exterior and interior dimension, payload, and towing capacities, and engine output is concerned. But both have different styling and packaging details and have nearly the same performance as well. Henceforth, if you want a bit more upscale Chevrolet, then the GMC Sierra 3500HD is a much better choice. 

RAM 3500 Mega Cab Diesel vs Ford F-350 Super Duty Crew Cab SB

The Ford F-350 Super Duty crew cab does not have a higher quality interior compared to the RAM 3500 Mega Cab but it does offer the best in class towing and payload capacity. Furthermore, it has a bigger fuel tank and also comes with an optional Tremor Off-Road package while there are no such off-road packages given by the RAM. 

2022 RAM 3500 diesel Mega Cab Final Verdict

If you want a fancy cabin, ample standard and optional features, and a decent driving experience plus performance the new RAM 3500 Mega Cab diesel is a deal for you. But if you can compromise the cabin material quality and design and go for more practicality then the Ford F-350 Super Duty crew cab is the best alternative available out there.
