For 27 years, the top-selling vehicle of any kind in the U.S. has been the Ford 150 pickup truck. But a terrific piece by Josh Levin at Slate suggests that its long reign may be coming to an end. Gas prices are of course one big reason: "As prices spiked above $4 per gallon in May and June, the F-150 was overtaken on the monthly sales charts by a bunch of puny sedans with good fuel economy: the Toyota Corolla, Toyota Camry, and Honda Civic," Levin writes. "With the 2008 F-150s failing to sell, Ford had to delay the launch of the 2009 model for two months while it pushed the previous year's trucks off the lot at deep discounts, cutting into those $4,000-per-vehicle profit margins/Jonathan Weber, New West.

Question: Do you drive a pickup truck? Did you consider trading it in when gas prices hit $4 per gallon?
