I have towed a ton with them, just make sure you don't get going too fast or tailgate anyone as the brakeing is going to take more time. Also a trailer with the weight balanced properly makes a hug difference when you are pushing the limits, car too far forward backwards or side to side can make for adverse handling, the tow rating is a safe limit that will acomadate some amount of improper load, if your really pushing the limits make sure it is centered good, strapped down good and tight and use trailer brakes if you can.
