You winterize for that one time when it freezes enough/ long enough for pipes to freeze, so doesnt really matter one day or 90 days, but, BUT....
Some people never winterize and are fine when pipe freeze solid, yet some have pipes burst.
The PEX pipes do much better than any other pipe.
Plastic water tanks take a very long time to freeze and are able to expand some, I have seen people store a full fresh tank for years in freezing winters.
Up to you, there are risk no matter what advice you get...

PEX probably isn't going to burst, but the plastic elbows and other fittings will if they happen to have enough water in them.

Theoretically, yes, but in practice I have yet to see one crack. The elbows dont contain a lot of water, it is a very small diameter pipe inside so much less pressure than would be on a bigger inside dia pipe fitting. 3/8 pipe fittings are small, even 1/2 might be small enough, bigger ones I am sure would prob crack. Most RVs are 3/8 that I have seen.

This is to notify new RV campers that pink RV antifreeze will freeze hard in winter time hard freezes. For instance like others I poured generous amount of antifreeze in my toilet bowel to stop the flush valve from drying out and the antifreeze froze solid one winter while RV was in storage in Reno, Nevada and yes the antifreeze is a 50/50 water mix. Just saying

No damage only stain from pink liquid. I did not use antifreeze in any other part of the trailer as I drained all water from tank and lines. antifreeze does not quickly evaporate like water is why I put it in toilet bowl.

RV antifreeze is not supposed to be diluted with water. Yes, the antifreeze will get slushy or possibly even freeze, but it will not expand like water which is what damages plumbing components.

We winter camped in the Poconos for a number of years. Had our RV on a permanent site. The water at the site was turned off, so no water ran through out water pipes, which we had drained before the cold weather hit. We also made certain all plugs were left open. We did use the drains of the sinks, and also the toilet (used gallon bottles of water to flush). At the end of each weekend, we would dump at our sewered site, and after closing the levers drop a gallon of cheap windshield washer fluid down each drain and the toilet to protect the levers from freezing shut. It worked perfectly. We would never leave any chance for water to freeze in the pipes. We used a large 60 cup coffee maker for our hot water and a 2.5 gallon plastic jug with a petcock on it for our cold water needs. Worked like a charm.

It suck to live at an elevation where it gets into the 20's for 4 days out of 20. Some times I leave the heater on set at 50deg and sometime I just bite the bullet and winterize
