Water line compatability?
In my 2015 Creek Side the fresh water plumbing is likely what everyone is using. It's somewhat translucent 1/2" CTS, joined together with "Flair-It" fittings. So, knowing only what I just mentioned,...

I have not done pressure plumbing on a trailer, but have a lot of experience with large power boats that also use Flair-It fittings. I love PEX. As Dave says, shark bite fittings work, but I like the Flair-It and use the custom wrench to tighten and loosen fittings. The secret I have found is to use a heat gun on a low setting. The fittings slide in and nuts go on with ease. Since the PEX and fittings are cheap, take a section of PEX and just test it and try it. You will be amazed. Also, try heating the PEX a little and bending. You may save an unnecessary elbow and one more possible leaking joint.
