I pull a single axle dump trailer. The trailer itself weighs 1300 lbs, and the trailer axle is rated to 5000 lbs. (You can have up to 3700 lbs load in the trailer.) I've had maximum loads a few times, and my Liberty does struggle, especially going uphill. For smaller loads, it does very well, and I hardly notice I'm pulling anything. Once I got my brake controller and trailer brakes adjusted properly, I also have no trouble stopping quickly.
I've never pulled a travel trailer, but based on my experience with a dump trailer, I wouldn't want to go on a long trip pulling something that weighed 5000 lbs. It wouldn't be fun. If you're planning to pull something lightweight like a pop-up, you shouldn't have any problems.
Also, be sure to check the owner's manual about the maximum square footage of the front of the trailer you want to pull. Even though your travel trailer might not weigh 5000 lbs, you will still struggle at highway speeds from wind resistance if the trailer is too big.
