The official answer is "Never exceed the vehicle's rating".
That means both the trailer weight and the tongue weight. I have no doubt that your Jeep can get that trailer moving. You should be more concerned about getting that trailer STOPPED. Rolling your jeep on the trail might ruin your day; rolling it on the freeway is going to really upset you and everyone within your immediate vicinity.
For the unofficial answer...
If I had to pull the family boat, I'm 5 miles from the lake, on quiet roads; the trailer has a good coupler-brake that actuates automatically, I'm keeping the speed under 25, and I've got a couple friends escorting me, keeping their vehicles between me and the general public. I would feel comfortable in that scenario, but I'd be much more comfortable behind the wheel of the 3/4 ton suburban we use for our regular tow vehicle.
As far as the Jeep itself - I'd be worried about the rear suspension under the tongue weight, the brakes and clutch under the extra load.
