The rated towing capacity is 6500 lbs. and if for some reason something does happen, Nissan will probably deny your warranty claim for abuse. Remember, lots of factors go into a maximum towing capacity, i.e. transmission, brakes, and the weight of the truck being three of the biggest! If the added load burns up your clutch or transmission, you may be out of pocket the repair expense! More important is safety! Being able to stop that 7300 lbs. load from a speed of 65 mph in an emergency is critical, not to mention what happens when a 7300 load decides it want to choose which direction the truck is going in an emergency maneuver! Physics plays a major role in determining the load rating of a truck. If it where me, I wouldn't chance it. If you’re the thrill seeking type, go for it! But do me a favor and post your itinerary before you leave so I can stay out of your way! 8O
