As pointed out above, here is the key - loading the car correctly to get the weight balanced on the trailer. If too much weight on the tongue or too little, the trailer will handle poorly and you could find yourself in trouble quickly and nothing you can do will bring back control of a combination out of control.
A trailer typically has a specific towing height at the tongue - typically 17 inches making it level. So if this height is known, you can then use a tape measure and measure from the ground level to the ball height. Load the car onto the trailer and watch the measurement. The trailer should be level.

I would also want a trailer with some kind of braking system as the extra weight will push you when going down grades or hills and could put you out of control. So if no brakes on whatever trailer you select, I would operate at reduced safe speeds and hope no jerk causes you to make a panic stop.
