It will probably have one. If not there will be a distribution block, probably near the fridge?
If it has a distribution block you will need:
1. Pipe dope rated for LPG
2. 1/4" Male brass pipe coupler
3. Quick connect female on trailer side
4. Propane hose with quick connect Male. Some are specific to the type of appliance you are using.
That should be it. Amazon sells a pretty complete package minus the hose.
2014's don't have a quick disconnect from the factory.
I installed an Extend-a-flow/Extend-a-stay fitting between the tank outlet and the regulator. Then after the regulator I plumbed in a quick disconnect to run my Camp Chef setup. The fittings and valve came from Home Depot, the quick disconnect came from Amazon. Link here: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
