Used 2020 RAM 3500 for SaleNationwide

How much does the 2020 RAM 3500 cost?

Prices have softened 11.96% compared to this time last year, making it a favorable time to shop this model year.

There are 860 listings available, which gives you a solid pool to compare prices and equipment.

Is the 2020 RAM 3500 a good car?

Yes — the 4.8/5 user rating points to strong owner satisfaction. Owners consistently praise its power and towing capacity, along with the comfortable interior and advanced features like the large display. For you, that means this truck fits especially well if you want heavy-duty capability without giving up everyday comfort and tech. With 29.1% of listings marked as good or great deals, there is still some room to shop selectively.

Is the 2020 RAM 3500 reliable?

Owners rate it 4.8/5, a strong signal of long-term satisfaction.

The owner feedback also points to a truck that feels dependable in the ways that matter most to heavy-duty buyers, especially when it comes to power and towing confidence. At the same time, some owners mention concerns around the CP4 pump and DPF filter, which can affect long-term ownership costs if maintenance is neglected. For used buyers, that means reliability can be strong, but you should pay close attention to service history and diesel-system condition if you want to reduce long-term risk.

What should I look for when buying a used 2020 RAM 3500?

At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can confirm accident records, title status, and maintenance patterns before you go any further. After that, prioritize a pre-purchase inspection, with extra attention to the drivetrain, emissions-related components, and any signs of heavy towing use. Because this truck is built for serious work, condition matters more than mileage alone, so focus on how well the truck has been maintained and whether it shows signs of hard use.

Is now a good time to buy a used 2020 RAM 3500?

This is a moderate buyer’s market, so you can shop selectively without expecting every listing to be a bargain.

• Deal availability: 29.1% of listings are priced as good or great deals.
• Inventory: There are 860 listings available.
• Price trend: Prices have softened 11.96% compared with last year.
• Clean inventory: 70.6% of listings are accident-free.

If you find a listing below $44,906, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 RAM 3500's resale value?

The current average of $44,906 sits slightly below last year's $51,005.

That price movement suggests the market has already adjusted downward, which can make the truck more attractive to you as a buyer but can also temper what a future seller can expect. If you buy at a strong price and keep the truck in clean condition, you may be better positioned to limit depreciation pressure later. Demand should remain supported by the truck’s capability and owner satisfaction, but resale will still depend heavily on condition, mileage, and maintenance history.

Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 RAM 3500 or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 29.1% of listings are priced as good or great deals.
• At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.96% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.

The bottom line:

The 2020 is a strong choice if you want heavy-duty capability, a more upscale cabin, and a market that currently gives you some negotiating room. If your priority is value, this year looks appealing because prices have eased and there are still plenty of listings to compare. If you are especially price-sensitive, you may also want to compare nearby years to see whether a slightly older or newer truck offers a better mix of condition, equipment, and asking price.
