In your case brakes will be required. Chevrolet/Workhorse says towing anything weighing over 1,000 lbs. requires it's own supplemental braking system. They don't get into the semantics as to whether a vehicle is considered a trailer. They say ANYTHING being towed weighing over 1,000 lbs. needs brakes.
Ford takes a similar stance in saying the chassis brakes are rated for the GVWR not the GCWR. They say brakes are required when towing anything weighing over 1,500 lbs. In short if you have a gas chassis you'll need a braking system for the Jeep.
We've towed a 2004 Wrangler automatic over 100,000 miles with no problems. We use a Roadmaster 9060 braking system. We chose it because of it's a truly proportional system, and there's only an air cylinder to install and remove. We wanted to stay away from the "brake in the box" systems that sit on the floor, and take substantial storage room when not in use. Our 2004 Wrangler Sport weighs 3,750 lbs. empty.
