Anything over 2000 lbs should have trailer brakes when being pulled with a Jeep. Somewhere I saw a weight ratio of vehicle weight vs. trailer weight that showed the percentage of weight of vehicle vs. weight of trailer in regards to whether or not you should have trailer brakes. I can't find it now, sorry. Also, having towed trailers of all different sizes and weights, I'd strongly recommend an automatic safety brake that engages should the trailer come loose from the hitch. They tie in to the pigtail and when the pin is pulled from the pigtail, the brakes automatically lock, stopping the trailer before plowing into you or oncoming traffic. Very much worth the investment.
