Is the 2020 RAM 3500 a good car?

Yes — the 2020 RAM 3500 earns a 4.8/5 user rating, which points to strong owner satisfaction. Owners most often praise its power and towing capacity, along with the comfort of the interior and the advanced features like the large display.

Is the 2020 RAM 3500 reliable?

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

The owner feedback also highlights dependable performance in the areas that matter most for this truck, especially power, towing, and comfort over long distances. At the same time, some drivers mention specific mechanical concerns, including the CP4 pump and the DPF filter, which can affect ownership costs if they show up in a used example. For used buyers, that means reliability can be strong, but long-term ownership risk depends heavily on maintenance history and how the truck was used.

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

At 70.7% 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 ownership patterns before you go any further. After that, prioritize a thorough pre-purchase inspection, with extra attention to mechanical condition and any signs of expensive diesel-related maintenance. Because this truck is built for serious work, focus on how it was used and whether wear matches the mileage and asking price.

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

This is a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 29.3% of listings are priced as good or great deals.
• Inventory: There are 863 listings available.
• Price trend: Prices have softened 10.52% compared with last year.
• Clean inventory: 70.7% of listings are accident-free.

If you find a listing below $45,339, 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 $45,424 sits slightly below last year's $50,767.

That price movement suggests the market has cooled, which can help you buy at a better entry point now but may also limit near-term upside if you plan to resell soon. For future sellers, the current trend means you should expect buyers to be price sensitive unless your truck has especially strong condition, equipment, or service records. Well-kept examples should still draw interest because this model year has broad appeal among shoppers who want serious towing ability.

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:

• 29.3% of listings are priced as good or great deals.
• At 70.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.52% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.

The bottom line: If you want the strongest mix of capability, comfort, and current market value, the 2020 is a sensible target. If you are especially price-sensitive, you may also want to compare nearby years and focus on the cleanest, best-documented truck rather than chasing the lowest sticker price alone.
