8. Dodge Ram Cummins
There were diesel trucks before the ’80s-’90s Ram Cummins, but they weren’t as good as this one. Under the hood was a venerable 5.9-liter straight-six diesel engine with only 160 HP but a healthy 400 lb-ft of torque. However, for the 1991 model year, Dodge updated the truck, giving it more power and options.
As a matter of fact, most diesel truck fans consider this to be the best year in the series. The power and torque figures seem low considering today’s engines, but this is an old truck with old technology. However, old technology doesn’t mean that the ’91 Ram Cummins is not a capable vehicle. With a 4×4 drivetrain, it is an extremely good truck.
