You'll be fine, though If you can find something lighter that's roughly the same size it wouldn't hurt. I towed my Evergreen Ascend trailer that had a dry weight of 4600lbs thousands of miles across Canada and the US with my 2015 V6 grand Cherokee with no issues. If you keep a close eye on payload and don't expect to zoom past anyone on the highway or fly up a steep hill or mountain you won't have any issues. People who try and tell you that you won't be able to tow that trailer with your jeep don't know what they are talking about.
