In the early '70s, just before the oil embargoes kicked off, Americans tended to drive massive land yachts. With the exception that rear wheel drive sedans have largely disappeared from the American carscape, not much has changed. Today, America drives huge pickup trucks instead.
Visually, the 2013 Ram 1500 has few visual changes from the outgoing model. Mechanically, however, they've finally brought Chrysler's big truck into the 21st century with a new ZF eight-speed transmission, adjustable air suspension, and a V6 that doesn't suck.
