PEX is amazing stuff as long as you keep it out of the sun, it does not stand up to UV well.
Mobile use? Every trailer that comes out of Elkhart is full of it…there’s a reason….it’s cheaper, easier to work with, and as long as you keep it out of the sun, it will last longer than your camper.
In researching, pex A is probably better….but it takes some expensive tools if you plan on any quantity. PEX A needs to be stretched before it is put on the barbed connector….it’s natural state is sealed. Where is crimp style are held tight by the rings.
In reality….I don’t think we’d ever see a failure rate worthy of concern in either case.
