From the Lubbock County Sheriff's Department:
In reference to inquiries about the use of the Chevy Tahoe in Law Enforcement:
The Lubbock County Sheriff's Office currently has 12 Chevy Tahoes in service by Law Enforcement Deputies, there are additional units assigned to Detention and Transport. These vehicles have much greater versatility, more room to accommodate an officer's safety equipment, higher trade in values, and they have a much better warranty plan (100,000 mile) which in turn, saves tax payer's money on repairs. This is compared to Ford's three year/36,000 mile warranty.
In addition to these benefits, the Tahoe offers better ergonomics across a broader spectrum of individual body types. Our Law Enforcement personnel find themselves spending countless hours behind the wheel of their patrol vehicles, patrolling over nine hundred square miles within the borders of Lubbock County. Their patrol vehicle is essentially a "mobile office" containing all of the essential equipment needed to conduct their daily duties. Anything to make their already stressful job less stressful is a plus.
The long term plan for the Lubbock County Sheriff's Office is to completely transition to the Chevy Tahoe as a standard patrol vehicle.
