You may want to check out the newer Dodge Durangos with the V-6. They have an 8 speed auto and three rows of seating. I believe the the V-6 and tow package they are rated to tow just over 6,000 pounds. With the Hemi V-8 it is over 7,000 pounds. However, you are likely to run out of payload before you run out of towing capacity.
My neighbor down the street has a 2014 V-6 Durango. he is towing some type of 25ft. Hybrid TT. he has traveled as far as Mackinac MI. He says it has plenty of power and performs well. he has no complaints!
