I believe that the National Laws govern tandem trailers on the interstate system...and it's allowed as long as you're under 65'. When you get off the interstates is when the state laws come into play. Note, however, I believe all require that the first trailer be a 5th wheel trailer (with the goose neck hitch that connects over the tailgate into the bed of the truck...or a semi truck arrangement).

Not sure if it's the feds or states (or some combination) that make the rules, but they are enforced by state officials (not feds). Tandem trailers are most definitely not allowed in all states, on or off the interstate.
It's sort of a moot point. If tandems are only allowed on the interstate, how would you get to the beach?
