Frequently Asked Questions - 3500 Chassis Cab (2020) RAM
What type of oil should I use for my 2020 RAM 3500 Chassis Cab?
For the 6.4L HEMI gas engine, use SAE 0W-40 or 5W-30 meeting Chrysler MS-6395. For the 6.7L Cummins diesel, use SAE 15W-40 meeting API CJ-4 or CK-4. Always check the owner's manual for the exact specifications.
What is the maximum towing capacity of the 2020 RAM 3500 Chassis Cab?
The maximum conventional towing capacity is up to 35,100 lbs when properly equipped with the diesel engine and 5th-wheel hitch. Actual capacity depends on cab configuration, drivetrain, and optional tow packages. Always follow GVWR and GCWR limits.
How often should I change the transmission fluid?
For the 8-speed automatic (gas), change transmission fluid every 120,000 miles under normal conditions. For the 6-speed automatic (diesel), interval is 100,000 miles. Heavy use (towing) may require more frequent changes. Use Mopar ATF+4 or equivalent.
What is the payload capacity of my 2020 RAM 3500 Chassis Cab?
Payload capacity can exceed 7,340 lbs depending on the specific chassis cab configuration (regular cab, crew cab, wheelbase). The exact number is listed on the door jamb sticker and must not be exceeded.
Can I install an aftermarket upfitter body on the chassis cab?
Yes, the chassis cab is designed for upfitting with a flatbed, service body, or custom box. Ensure modifications do not exceed GVWR and GAWR. Use certified upfitters and follow RAM's body builder guidelines.
What is the recommended tire pressure for the RAM 3500 Chassis Cab?
Recommended tire pressure is typically 65-80 psi for the front and 70-80 psi for the rear, depending on load. Always check the tire placard on the driver's door jamb for your specific tire size and load.
How do I reset the oil life monitor?
Turn ignition to RUN (do not start). Fully press the accelerator pedal three times within 10 seconds. Then turn ignition off. When restarted, the oil life should show 100%. Refer to the dashboard menu for a more detailed procedure.
What is the difference between the 3500 and 2500 RAM trucks?
The 3500 has a heavier GVWR (typically 10,000-14,000 lbs vs 8,800-10,000 lbs), higher payload and towing capacities, and often a rear leaf spring suspension instead of coil springs. The chassis cab version is even more specialized for commercial use.
Where can I find the VIN number on the 2020 RAM 3500 Chassis Cab?
The VIN is located on the driver's side dashboard (visible through windshield), on the door jamb sticker, and on the frame rail near the front passenger side. It is also stamped on the engine block.
How do I properly maintain the diesel engine's emissions system?
Use ultra-low sulfur diesel (ULSD) and the correct diesel exhaust fluid (DEF). Regularly check the DEF level and refill when low. Avoid frequent short trips that prevent the diesel particulate filter (DPF) from regenerating. If the DPF light comes on, perform a stationary regeneration by following the prompts in the instrument cluster.
