Yes! The area behind the rear seat is very useful. The third row folds flat into the floor so there is no moe wrestling the bench in and out of the vehicle. That feature may have been around for some years, I am not sure.
As far as towing, I wish I had a TT to try it out with. I would have for sure. The 3.08 rear axle is rated for 8300 lbs. what I can say is this thing will flat run and it doesn't feel like the 3.08 rear gears of old. I am not sure if there is something to the 6 speed or not.
However the 8300 lb rating is nothing to sneeze at.
I was concerned about the mirrors too. They are adequate but do have a fisheye blind spot mirror built in to the drivers side mirror. I would prefer a set of dumbo ear mirrors but that's just me.
The drivers seat wasn't nearly as comfortable as 90% of the chevy seats I have used. GM seats are generally VERY comfy however this seat is the exception. The seats were stiff and after 300 miles one way I was thankful my trip was over. Even my wife commented about how uncomfortable the seats were.
The 2015 Expedition will have a HD version that will be rated to pull over 9,000 lbs from what I understand. I'm not sure how much payload it will have but if it's close to 2000 lbs then it may be a suitable replacement for many 2500 Suburbans...just with the wrong nameplate.
Thanks!
