Towing Doubles

Thanks everyone who replied. Be advised I have scoured the statutes in both Alabama and Georgia, and can find no prohibition. This is why I asked for specific statutes in those states if anyone was aware of them. The references some suggested I use claim it is illegal in these two states, yet I find no prohibition in any if my research. Also, for the purposes of this discussion, even though the definition has been discussed to death, I refer to it in the same scope as the State of Michigan, where I am licensed and registered. In Michigan, it is referred to as towing 'Recreational Doubles'. Also, I have read about all those who tow doubles in Florida with no issues. Well, leave it to me to encounter an FHP trooper with trainee in tow, as he taught her how to 'write tickets'. I have calls and written requests in to both Alabama and Georgia DOT's for a determination, and am getting no where. I just thought there might be someone familiar with the specific laws in these states who could shed some light.
