Things are looking pretty good for truck buyers these days. Gas prices are going down and there are three excellent full-size trucks to choose from. However, the big game changer is the 2015 Ford F-150 and its lightweight aluminum body. Sales of the outgoing F-150 have remained strong, but sales of the Chevrolet Silverado and Ram 1500 have also been solid. While Ford makes the changeover to aluminum, its two Detroit rivals have been enjoying increased truck sales on Ford's behalf.

According to a new report from Automotive News, the Ford F Series, including the Super Duty models, remained in first place last month, despite a one percent sales drop. However, if you were to include both the Silverado and GMC Sierra, GM sold more large pickups than Ford overall for the second consecutive month. The Silverado experienced a 54 percent gain and the Ram 1500 had a 30 percent surge. In fact, Ram sales helped the Chrysler Group outsell Toyota USA for the first time in three years. That's quite an accomplishment. But perhaps this should all be considered as the proverbial calm before the storm.

Just one of Ford's two F-150 plants is up and running at the moment while the other is being prepped to build the new model. Very soon both will be churning out the latest generation of America's best-selling truck. Chevy and Ram's sales surge may not last much longer.
