Hello, Thinking of a 2015 Unlimited Altitude Edition Jeep to use for work. Will the 3.21 axles be ok for a 3000 pound cargo trailer? The weight is the loaded weight. The trailer is for occasional use, maybe 5 days a month. The dealers advice is sure it will tow anything. Thanks for any advice. The Jeep has a tow package on it from the factory, however it is not the max tow package.
