The 4th gen RAM gained the best interior in its class and a properly modern Hemi, but the 8-speed transmission introduced mid-cycle has a documented judder issue that Chrysler settled a class action over.

The 3rd gen RAM 1500 is the affordable domestic truck pick if you go 4.7L PowerTech or 5.7L Hemi, avoid the 3.7L V6, and inspect the front end components carefully on anything above 100k.

The 2nd gen RAM is the old-school Mopar truck, Magnum V8, simple enough to fix in a driveway, and priced under $5k, but frame rust is the single inspection item that ends deals.
