We have a 2011 with the V6 tow package, max towing capacity rated at 5,000 lbs. We pull our X9... and well to be honest its not enough. The only reason we continue to do so is because its the vehicle we get though work and don't want to have two SUV's. When you give it gas it pulls hard to the right in FWD or 4WD sand. If we go say 60-63 mph it gets about 12 mpg anything over it is around 5-8 mpg. If you have any other specific questions please feel free to ask
As for you I would say it is fine. Our boat is rated at around 3k plus the trailer so we are at the max.
