Three trims are available – LS, LT, and LTZ, though a Z71 is slated for later in the model year. Among the features found on the 2007 Chevrolet Avalanche are a rear park assist system, a rearview camera, a new touch-screen navigation system, an upgraded rear DVD system with an eight-inch screen, and a remote-starting feature. There’s also a central locking tailgate controlled by the door switches or the keyless remote, and optional side-curtain airbags for both rows.
