Nissan's full-size underdog runs a bulletproof 5.6L V8 that'll hit 200k miles while costing $10-15k less than an F-150. The hydraulic steering and column shifter feel refreshingly analog, the warranty is class-leading, and owners who ignore the badge report trouble-free ownership. The 2016-2018 models had a cylinder 7 scoring issue, warranty-covered and fixed by 2019, but the bigger problem is fuel economy that makes other half-tons look thrifty and an interior that feels a decade behind. The rare 5.0L Cummins diesel is a disaster; stick with gas. Buy this if you want a simple, capable workhorse and don't need to flex at the job site. Skip it if resale value or cutting-edge tech matters, or if you're shopping 2016-2018 without extended warranty coverage.
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.
