2007 Nissan Armada SUV SE 4dr SUV (5.6L 8cyl 5A)
Forget the others, buy the Armada!
 After going back and forth between the Armada and the new Tahoe we finally decided on the Armada.  No regrets at all.  Tons of power to tow a 6500 lb boat.  I'm 6'5" tall; the Armada was way more roomy for me and for the rest of the family.  My wife and I really liked the standard features (too many to list) over the competition.  Best bang for the buck.  Way to go Nissan!
