Could the reign of Ford's F-Series atop the sales charts in the U.S. come to an end? Some believe that it could indeed happen, and it's not even another pickup truck that is threatening the Blue Oval's bread-and-butter full-size pickup, it's the Toyota Camry. Let that sink in for a moment... alright, let's continue. The Camry already posted better sales numbers than the Chevy Silverado, the perennial second-best seller to the F-Series, for the month of April. In fact, the Silverado suffered a sales drop of 24.7 percent to 37,231 units while the Camry grabbed 40,016 sales in the same month. Still, even after the Camry's great sales month, the Silverado holds the edge when the entire year-to-date sales numbers are compiled, and the F Series still sits atop the list for now. Consider too that the Ford truck will get a major redesign for the upcoming model year. So, while high gas prices will likely continue to put pressure on full-size pickups, let's not jump to hasty conclusions just yet.
