I purchased the Rainier because I needed a vehicle that had the hauling capabilities once in a while.  90% of the time, I use it for a daily driver.  But on the weekends, I enjoy working in my yard and needed something that can get the job done.  Very pleased with this vehicle, very comfortable and quiet ride.  In addition, lots of cargo room.  I'm averaging 18.5 miles (mostly drive highway), but I was expecting a lot worse.  It is an SUV and does weigh close to three tons!  If you need a vehicle with towing/hauling abilities once in awhile, the other times a vehicle that does not punish you in a daily commute, I Highly Recommend this vehicle.  Keep in mind, it is an SUV and like all SUVs, regardless of make, it will cost you at the pump.
