SharkBite fittings are the way to go. No muss or fuss. They work on pex, pvc, and copper lines. I have used them in my previous rv and in my house. No soldering, no crimping, no leaks!
I have never used these,but have watched their videos plus a segment of This Old House featured them. If you can believe their videos,etc,plus your endorsement,I guess they work well. Their videos show many different types of valves in addition to the fittings.
