What is the correct order of operations for coupling a complete triple-trailer (triples) rig from scratch?

Question

Accepted Answer

Couple the tractor to the first trailer using the standard tractor-semitrailer method, then move a converter dolly into position and couple the first trailer to the second trailer using the twin-trailer coupling method, then repeat with a second converter dolly to attach the third trailer

Answer

Couple all three trailers to each other first using converter dollies, then back the tractor up to the completed three-trailer string last

Answer

Couple the tractor to the trailer that will end up in the rear position first, then work forward attaching trailers toward the tractor

Answer

Use an entirely different, triples-specific coupling procedure that does not reuse the doubles coupling steps
