The 2020 Ram 4500 is a heavy-duty chassis cab truck built for serious work. It’s part of Ram's commercial vehicle lineup, known for its robust capabilities and durability. Available as a chassis cab only, it allows for customization with various upfits. Key trims often involve different GVWRs and equipment packages tailored for specific jobs. The pricing ranges significantly based on configuration and upfitting. It's popular due to its immense towing and hauling capacity, powerful engine, and relatively comfortable cabin for a work truck.
The Good

The 2020 Ram 4500 excels in performance with its immense power and towing capacity, appealing to practical buyers. While not luxurious, it offers a relatively comfortable cabin for its class. The strong, purposeful design inspires confidence. Reliability is generally good, though maintenance is crucial. For emotional buyers, it represents capability and dependability, a true workhorse.

The Bad

The 2020 Ram 4500's weaknesses include its size, making it difficult to maneuver in tight spaces. Fuel economy is inherently poor due to its heavy-duty nature. Maintenance can be costly, especially for diesel models. Potential buyers should watch out for issues related to the emissions system and ensure proper upkeep of the transmission and brakes due to the stresses of heavy towing.

What Problems Does the 2020 Ram 4500 Have?

Frequently reported problems for the 2020 Ram 4500, and similar model years of heavy-duty Rams, often revolve around the emissions systems, particularly on the diesel models. Issues with the diesel particulate filter (DPF), diesel exhaust fluid (DEF) systems, and related sensors can lead to warning lights, reduced performance, and costly repairs.

Transmission issues, especially with the Aisin automatic transmission used in many heavy-duty applications, can occur if the truck is consistently used for heavy towing without proper maintenance. Regular fluid changes are crucial.

Brake wear is another common concern, given the vehicle's weight and towing capacity. Frequent inspections and timely replacements of brake pads and rotors are essential for safety.

Electrical issues, while not widespread, can occur, including problems with sensors, wiring harnesses, and the infotainment system. Checking for recalls related to these components is advisable.

Recall information should be checked via the NHTSA website using the VIN. While specific model year issues might not always be prominent, staying informed about any recalls related to safety or emissions is crucial for maintaining the vehicle's reliability and longevity. Long-term reliability depends heavily on proper maintenance, especially concerning the engine, transmission, and braking systems.

How long will the 2020 Ram 4500 last?

The 2020 Ram 4500, when properly maintained, can easily provide 200,000 to 300,000 miles of service or 10-15 years of reliable use. However, this relies heavily on consistent maintenance, including regular oil changes, transmission servicing, and brake inspections. Key to longevity is addressing potential issues promptly. Long-term durability can be affected by rust in colder climates and stress on the drivetrain from constant heavy towing. Weaknesses often surface in the emissions system (diesel models) and electrical components over time. Proper care ensures optimal performance and lifespan.

What Technology & Safety Features are Included?

The 2020 Ram 4500 offers a functional but not overly luxurious set of tech and safety features, prioritizing utility over advanced technology. Standard entertainment features typically include a basic AM/FM radio with a small display screen. Upgraded trims or option packages may offer a larger touchscreen infotainment system with Apple CarPlay and Android Auto compatibility.

Driver-assistance features are generally limited compared to passenger vehicles. You might find features like electronic stability control, traction control, and trailer sway control as standard. Optional features can include a rearview camera, which is extremely helpful given the vehicle's size and potential for blind spots.

Safety features include standard airbags, anti-lock brakes, and seatbelts. Due to the commercial nature of the vehicle and its chassis cab configuration, the 2020 Ram 4500 is not typically subjected to comprehensive crash testing by organizations like NHTSA or IIHS. Therefore, formal crash-test ratings are generally unavailable.

The focus is more on providing basic safety and utility features to ensure safe operation for work-related tasks. Features like upfitter switches for controlling auxiliary equipment are also common. The availability of specific features often depends on the chosen trim level and optional packages selected when the vehicle was initially configured.

2020 Ram 4500 Prices and Market Value

The 2020 Ram 4500, when new, typically ranged from $45,000 to $60,000 depending on the configuration, engine, and upfitting. Current used market prices can vary widely based on mileage, condition, and the type of upfit installed. Expect prices from $35,000 to $50,000 or more. Depreciation is affected by factors like mileage, maintenance history, and the specific industry the truck was used in. Trucks used in demanding applications may depreciate faster. The presence of desirable upfits can also increase resale value.

2020 Ram 4500 Cost of Ownership

The 2020 Ram 4500 is generally costly to own. Insurance premiums are higher due to its size and commercial use. Fuel costs are significant given its poor fuel economy, especially with the diesel engine. Maintenance, including oil changes and brake replacements, can be expensive. Repairs, particularly related to the diesel emissions system or transmission, can further increase long-term costs. It's not an economical vehicle, but a necessary expense for businesses requiring its capabilities.

How Does the 2020 Ram 4500 Compare to Other Pickup Truck?

The 2020 Ram 4500 competes primarily with the Ford F-450/F-550 Chassis Cab and the Chevrolet/GMC 4500HD/5500HD. In terms of performance, all offer similar towing and payload capabilities, with the choice of gasoline or diesel engines. Ram often receives praise for its interior comfort (relative to competitors in this class) and user-friendly infotainment systems.

Reliability is a mixed bag across all brands, with each having potential issues related to emissions systems and transmissions. Price points are generally similar, varying based on upfitting and specific options.

The Ford F-450/F-550 offers a strong reputation for durability and a wide range of upfitting options, making it a solid alternative. The Chevrolet/GMC 4500HD/5500HD provide a similar level of capability and a slightly different styling approach. Ultimately, the "best" choice depends on specific needs and preferences, as well as the availability of reliable service and support for each brand in your area. All are capable work trucks; it often comes down to brand loyalty or specific upfitting requirements.
