In a standard doubles combination, what is the correct order for coupling: dolly to trailer, or trailer to dolly first?

Pick an answer

1. The order of coupling never matters as long as everything ends up connected in the end since the tractor's fifth wheel is assumed to hold everything together on its own
2. The converter dolly is typically coupled to the second trailer first, then the dolly assembly is coupled behind the first trailer
3. Coupling order is determined solely by trailer color
4. The second trailer is always coupled directly to the tractor first
