2" is a pretty mild lift, but the 33" tall tires are going to suck up some of your power unless you changed the axle gearing to match.
The Jeep itself would be more than rated to tow that little trailer in stock form. With the 4.1L and Class 3 hitch, it probably is rated for 3500lbs.
The only real questions are with the suspension mods and 33" tires. Did you make mods that let the Jeep articulate over the terrain? If so it will not deal well with the trailer shoving it around.
Frankly, you are not going to destroy the universe if you give it a try. You already have the trailer, and the Jeep, right? Hitch it up and see how it looks first. If the Jeep still sits fairly level with the trailer hitched, take it for a run around the block to see how it feels.
