Supply lines?? Supplying what? Sorry not sure about your question.
OK I will explain. My 2007 class C had a Dometic fridge. This fridge worked just fine at 10000 feet no problem. However my 2016 Domestic was going out at 8600 feet. One of the differences is the 07 had copper lines and the 16 has "all" rubber lines. Why does this matter? Well here are the fact's 1. At higher altitude the mix goes a bit rich. 2. The colder propane gets the more dense it becomes. 3. A rubber line will contract when it gets cold. The copper line not so much. During the day the unit would spit and sputter and it would continue to spark. After a few minute's it would settle down and go quiet. At night it would go out. It would relight after a few trys. I took it apart and watched the flame. The flame was lifted off the burner. This is why it would continue to spark. It did not have a path to ground so the control board believes it was not lit. It is my theory that when the hose contract's the pressure raises enough to over pressure the flame and given a bit of time the pressure drops and the flame goes normal.
That answer your question?
