#10 of 10in Heavy-Duty Pickup Truck (Class 3)

520 sources · updated June 2026

The Ram 3500 is a truck built around one of the best diesel engines ever made, wrapped in a body that can't quite match it. The Cummins 6.7L will run to half a million miles with religious maintenance, but electrical gremlins and corrosion show up embarrassingly early, one owner found corroded connectors at 2,500 miles. Spec the Aisin transmission and budget for DEF system upkeep, and this truck will haul 36,000 pounds until the sun burns out. Buy it if you need maximum capability and can wrench or afford a good independent diesel shop; walk if you expect Toyota-grade fit-and-finish or can't stomach chasing electrical faults.

The generation that matters

This product isn't one story — here's how each era is regarded.

3rd generation (2009–2018)

2009 – 2018

Mixed

Known for rust-jacking brake hoses (especially 2009 models), electrical gremlins, and front driveshaft failures. The Cummins engine itself is praised for durability (500k+ mile examples), but the truck around it has quality issues.

4th generation (2019–present)

2019 – 2024

Compromised

Quality has declined significantly per techs — corrosion on brand-new trucks (2500-mile example), cheap materials, persistent electrical faults. The Cummins remains strong, but build quality is 'really bad now' according to Chrysler techs.
