Tow, Tow , Tow your boat.
 Sold the 01 Ford F250 diesel (lots of problems). After comparing the others we bought the Armada. Nissan has the best tow and feature package in the market for the money. Towing a 6000 pound boat takes a little horsepower, and oh, does the Armada have the horsepower. I read about poor gas mileage in reviews, the Ford got 12mpg pulling the boat, the Armada gets 13mpg. Highway mileage is 20 at 70-75mph and city is 15, if you keep your foot out of it. It's comfortable, smooth, Lots of convenience features,a lot of bang for the buck. Air suspension and trans gauge is standard with tow package. Nissan has thought of just about everything, my wife LOVES her Armada, its our 5th Nissan product.
