The dash display is a clean looking design and an easy read, day or night. A GPS based navigation system is available optionally. My test truck was not so equipped, and the center dash cluster was uncluttered and straight forward, requiring little diversion from your driving to adjust temperature and sound. Speaking of sound, there’s a step-up Bose system available, it’s a healthy price bump - $495 – but also a nice quality unit. With six speakers, a six disc, in dash CD player and 275 watts of power, it’s worth a listen before deciding. A rear seat DVD system is also on the option sheet to keep those in back entertained. The second row will take two to three adults in good comfort. Rainier is a mid-size; no third row seat is offered. This frees the rear compartment to hold a generous amount of cargo. There is 39.8 cubic feet of room in back, accessible through a top swinging lift gate. The opening is wide, the hold is large and lift over height is low. Capacity expands to as much as 80.1 cubic feet, depending on how many of the split back seats you choose to fold.
