I agree with Beech on this one. I loved my old '85 Ramcharger; it was rugged as hell, tough as nails and destroyed any trail or load I handed it, mostly thanks to its suspension/drive train that was virtually unchanged from the old WWII Power Wagon.
BUT, I've driven several Dodge full sizes owned by relatives and found them to be just as tough. More importantly, they are WAY more powerful and more comfortable for daily living, let alone driving. Hell, my '96 Dodge Dakota's 3.9 magnum V6 is more powerful by far than the 318 in my old Ramcharger, and gets about half again the mileage.
Lets be clear on this: America loves pickups, especially full size pickups. While Japanese small pickups do well here, their sales numbers do not in any way approach the sales figures of the Big 3 full size trucks. And lets not even talk about the Tundra and the Titan; their sales figures are so low that Nissan considered rebadging the Ram r/t spend even more money to develop the next gen Titan, and the Tundra facility is nowhere near its production capacity. After decades of industry leading sales (the number one most sold vehicle in the world? Ford F series, Chevy Silverado is not that far behind it, and the Dodge Ram has placed in the top 10 sold in the US since its '94 redesign) the Big 3 give Americans exactly what they want in a pickup.
