Does anyone know the regs on pulling doubles in Ok.? I have a little 19ft bumper pull travel trailer that I'm wanting to hook a boat to. One of my boats is a 19ft toon, the other is a 14ft jon. Some say you can only pull doubles if the first trailer is a fifthwheel or gooseneck. I have also heard that if your vehicle tow rating is enough it doesn't matter what type of trailer it is. Anyone know?
