File Security and Access Rights. Because files are securable objects, access to them is regulated by the access-control model that governs access to all other securable objects in Windows. For a detailed explanation of this model, see Access Control. You can specify a security descriptor for a file or directory when you call the CreateFile, CreateDirectory, or CreateDirectoryEx function. If you specify NULL for the lpSecurityAttributes parameter, the file or directory gets a default security descriptor.
The typical width is usually 50 and 60 inches. A good example of a pickup with standard bed dimensions is the GMC Sierra. Its bed is 50 inches wide and 6.5 ft long. You can also use a Nissan Titan because it has a standard bed. Its bed is 60 inches wide and 6.5 feet long.
One thing to consider is how big you want your truck to be. Many pickups don't offer their longest bed in crew cab guise, as most crew cab shoppers aren't looking for the practicality of a huge bed. Trucks that offer both a crew cab and a full-size bed are extremely long and, as a result, hard to maneuver.
