| Gas Engine Maintenance |
Gas models may be simpler to maintain for buyers who do not need maximum diesel towing capability. |
Check oil change history, fluid service, engine condition, cooling system, and overall service records. |
| Diesel Engine Maintenance |
Diesel models can offer serious towing strength but may require more specialized maintenance. |
Review fuel filter service, DEF system care, emissions components, turbo behaviour, hard starts, and diesel service history. |
| Tires |
Heavy-duty trucks can wear tires faster when used for towing, payload, gravel roads, or work use. |
Check tire tread, tire age, load rating, uneven wear, alignment history, and replacement cost. |
| Brakes |
Towing and heavy payload can increase brake wear over time. |
Inspect pads, rotors, brake feel, vibration, service records, and towing-related brake wear. |
| Transmission |
Smooth shifting is important on a heavy-duty truck, especially one used for towing. |
Watch for rough shifts, delays, leaks, warning lights, diagnostic codes, and transmission service history. |
| Suspension and Payload |
Heavy loads can add wear to suspension, steering, and frame-related components. |
Check shocks, springs, steering feel, bed wear, alignment, payload history, and signs of commercial use. |
| Rust and Underbody |
Road salt, winter moisture, gravel, and age can affect long-term condition and repair costs. |
Inspect the frame, rocker areas, wheel wells, brake lines, suspension mounts, hitch area, and underbody. |
| Used Truck Condition |
A used Ram 3500’s maintenance cost depends heavily on previous ownership and how the truck was used. |
Review service records, towing history, accident history, warning lights, recalls, and inspection results. |
