We are researching best way to tow a Honda Goldwing trike behind a fifth wheel and be legal in all states. Would like to hear from anyone with experience and advice on this subject.

Different states have different laws, length laws, cdl requirements etc...
As far as triple towing in a state that doesnt allow it, do so at your on risk. If pulled over most will make you unhook the trailer right there and leave it until it can be towed legally.
