If you are at the age where you are shaking your fits and saying, "you kids get out of my yard?", then it is right to panic about all this. In reality, people go way over the rating all the time and it works. Diesel p'ups sometimes tow 30,000lbs which is way way over the rating. When Dodge says, 6,000lbs rating, they will likely assume you are not adding the weight of the passengers or stuff you have in your truck/suv already. They reduce the tow rating by what they assume will be in the truck because people sue so readily over things that are the drivers fault, and win. So, Dodge says to themselves, this suv can tow 9,000 lbs, but we know people will over load a 6.000 dry weight trailer and not know it is heavier than the stated 6,000 lbs, and they will also over load their suv with weight and not consider this weight either, so let's state the tow rate at 3,000lbs less so it is dummy proof...
Stay within reason with weights, and your trailer is within reason, drive carefully, get a good feel for what you cannot do with the trailer and enjoy your trip.
