what do I do Here?

I could be all wet (pun intended) but I believe most PEX is not UV stabilized.

It's still dumb to extend a potential pressurized line outside the camper.

It's not "pressurized."

Worst case if it fails the water runs out of your fresh tank at an excruciatingly slow rate. It's not going to spray or squirt, and as you've seen by this thread, repair is extremely simple.

Correct.

I'm not sure I understand why that's dumb joeshmoe. They seemed to work fine. The only time I used them was when I winterized. Why is that dumb? And please don't make fun of my ignorance as seems to happen sometimes on this website. Before I started this I didn't even know what PEX or a Flare-it fitting was. The only way I learned was by asking "dumb" questions. thanks in advance for your answer.

A plastic, pressurized line exposed to the elements is generally not a good idea. It's one of those things that should not be a problem, but the builder made it a problem by putting it out there. However, I've been in and around plumbing repair for 25 years. I'm a little biased.

For me I always saw the drain lines as being easily broke because ours hang down a good 12-14" outside-free in the breeze. Luck is haven't yet. The lines themselves go up inside rear skirt cabinet to wing floor, 36" or better.

The dumb part, in my opinion, other than too long, is the outside length being full of water, subject to freezing- no way to address should they just break or burst.

I don't live nor camp where freezing would be concern. I don't use tools to loosen or tighten the drain caps and location actually would be hard to whack. So they work.

If I ever addressed I would shorten considerably. Adding valves inside the cabinet where line pass doable but unheated so unsure resolve much.If they broke while out would be inconvenient at worst, I can access water in tank or pump into a bucket from broke line.

Dumber in my opinion is no endpoint valves anywhere in our camper except water heater. If I were to add valves it would be at sinks and toilet, likely toilet 1st to throttle it.

Thanks to everyone who responded. I fixed it for under 20 bucks (flare-it valve and pex cutting tool). Like most stuff with a camper to me, it seemed daunting to try it myself but ridiculously easy once I knew how. Thanks to you folks!

Just went through this cutting down a tube for a new toilet. The flair-it worked like a charm, even in a very tight space.

Ours has no valves before end of low point drains. End caps are the 'valves', loosen or completely unscrew.

I think the OP just wants to put it back the way it was. The part looks like this $4 one Why spend $70 or even $12?

He might as well buy a couple and replace em both
