I towed a 76 Bonair pop up tent trailer last year on a cross country road trip. The trailer has no brakes, is about 12' long and is fairly heavy when loaded. There is a bit of trailer sway on the highway as the trailer sags to one side because of a frame failure on a pothole. The Jeep gets horrible mileage while towing but handles the load rather well. The trailer suffered a blow out at about 60 MPH and the Jeep kept dragging it like nothing happened.
Here is a partial pic of my trailer............finally.
