I installed 3/8” copper lines that will supply propane to each appliance: heater, refrigerator, and stove.  I used a flare tool to shape the ends of each copper line.  I doubled flared all the connections and tightened them with brass flare nuts.  After running all the lines, I used soapy water to test each connection for leaks.  The lines are run, no leaks, time to move onto the next task.

I am definitely tired of crawling under the trailer.  I never thought I would be so happy to have a scrap of carpet.

Bending Spring to keep pipping from kinking.
