PEX is the way to go but be aware there are several types of PEX each with there own fastening systems and they don't play nice with each other. I prefer the expansion style of PEX fittings which are much easier to use in the tight recesses under our coaches then the compression ring style. One brand name of the compression style is Power Pex. The different types are designated as A, B, and C. I don't recall off the top of my head if the expansion fitting type is A or B.
