Not surprisingly, stepping up and into the Chevy Avalanche’s rear seat is made easier with the help of side running boards, just as the case is with the front seats. Once inside the truck, rear passengers are granted plenty of overall room, though taller riders may find their knees rubbing against the slightly padded front seatbacks. Armrests and door sills are properly positioned to be useful, however the small headrests rise only a few inches, making them worthless for most rear seat passengers. A fold-down center armrest is a bonus with two rear occupants, but when raised serves as an uncomfortable backrest for a passenger relegated to the center position.
