Question:

I want to be able to haul my 2017 Montana 5th wheel RV with my 2016 Freightliner semi truck. What do I need for electrical connections?

I'm going to assume you don't have any trailer wiring as you didn't mention any, so what you can do is add the Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End # HM47210.

On this 7-way, the white wire is ground, yellow is left turn signal and brake lights, green is right turn signal and brake lights, brown is the tail light wire, red is auxiliary power, blue is output to electric brakes, and purple is reverse lights.
