I'm looking for suggestions on how to find out the legality of towing two trailers in various states(MO,IL,KY,TN,GA,FL specifically) regarding what configurations are legal. I need to take a couple of extra bikes to Bike Week this year, so I'd like to pull a small utility trailer behind the TT. The only thing I've heard that is relatively universal is 65' overall length, which shouldn't be a problem. Any suggestions would be appreciated.
