This is my first post on the site; I hope its helpful.
Here is a video I referenced to convert my Coleman Roadtrip to the trailer LP QC. The parts thread to gather no problem.
As a safety note your hose should end with the female QC. The male end should always point towards the supply.
If the connectors somehow come apart; the female end stops the gas flow and the male doesn't.
We had an occurrence at work where the end of an air hose was a male QC. When they suddenly became disconnected we had the male end whipping around and it hit someone in the head requiring stitches.
The PSI is much lower and it won't whip around but the gas will continue to flow if the end is the male QC.
