Claims rate: 6.8 per 1,000 vehicle years The Silverado 1500 Crew Cab had the largest absolute volume of 2012 theft claims of any model at or near the top of the HLDI's list. But the big number of Silverado Crew Cabs on the road managed to dilute the truck's claim rate enough to put the Chevy in second place on this year's rundown. Once again, Moore blames the Silverado Crew Cab's popularity with burglars on the model's open truck bed and frequent time spent unattended at construction sites. "Heavier-duty trucks and/or those with crew cabs are more likely to be job-site vehicles," he says. HLDI figures show that insurers spent $5,463 on the average Silverado Crew Cab theft claim last year. That boosts the typical vehicle's annual insurance cost by around $37.
