Claims rate: six per 1,000 vehicle years Moore believes that like the F-350, the GMC ( GM) Sierra 1500 Crew Cab makes the list because it's a big pickup with an open truck bed and often sits for hours at construction sites. Again, that's the perfect situation for crooks. "Being a larger vehicle, the Sierra is more likely to be used on a job site -- and it has a bed that's easy to take things out of," he says. Last year, insurance firms paid out $6,366 on the average Sierra Crew Cab theft claim. That averages out to an extra $38 a year for every 2010-12 Sierra still in service.
