Not usually and issue we have to deal with around these parts and fuel stations don’t change fuels in the winter. However I will be traveling for a week to where the overnight lows are just below freezing (around 29F) and highs are in the 40s.
I was planning on using some PM22 but wondering if it would be advisable to use PM23 instead or if I will be alright at those temps.
quick google search says cloud point of #2 is around 14 to 17F
I am in the mid-Atlantic region and we do have periods of below freezing. As a preventative, I am using Hot Shots Secret Winter additive this season, based on positive results of using their Everyday Treatment during the summer. The formula has an anti-gel in addition to lubricity and cetane improver. The fuel is already treated for winter, however, I feel more comfortable adding to it. Just my opinion and I'm sure others will chime in shortly with what works for them.
I haven't needed an anti-gel in quite a while but I run Stanadyne additive for the other benefits. I would run it because #2 will cloud around 32 degrees and probably won't gel until you hit 15 degrees or so. If it looks like it will freeze I would run an anti-gel product just because weather guessers have been wrong before. It comes under the heading of better safe than sorry.

Any reason not to run both the cetane booster and antigel? I will be towing heavy and I have yet to use an additive. I’ve noticed a drop in MPGs lately and was going to pick up an additive which is what sparked my original question. Just not sure which one to get or if I can run both in the same tank?

I have read nothing but good things about EDT just hesitant to use anything other than motorcraft due to warranty
If I plan on traveling into a cold climate, I will start treating the fuel before I get there. For years, I ran this:
About two years ago I switched over to Opti-Lube XPD as I can run it regular strength all year around and if I drive into very cold areas, I just double the dose and it gives me plenty of protection... so far
Now that all of my local truck stops are switching over to "renewable" diesel, not sure I will continue to treat the fuel. Most likely will but may no longer be needed.

Good luck NOT finding winter blend fuel.
The reason why your MPG has dropped is cause winter blend provides less BTU.....IE, your most like running winter blend fuel already.

The Stanadyne does both as well as clean and lube fuel system components if the advertising is to be believed. I run it half strength or so during the summer and full strength in the winter for the cetane boost and maybe get a smidgen of my mpg loss back.

I don't worry until 0F.
I thought that might be the case since there are only so many refineries. However, I am in SoCal so I wasn't sure. I’ve never seen or heard mention of winterized diesel out here.
I just picked up my truck in September but have been running Optilube XPD in every tank. It seems like it does quite a bit of everything… but like mentioned above, I’m sure most of the big brands will all perform pretty well.
We get a few nights in the single digit temperatures every winter here in the central Shenandoah Valley of VA, so I add PM 23-a in the winter as a precaution. PM 22-a is added in the summertime.
Unless your tank of SoCal fuel will take you all the way to winter country, you should not need an additive. ALL of the cold weather states have long since gone to a winter blend. Buy a tank of fuel when you arrive, dirve it enough to get it in the system, then don't worry. I have started lots of diesels with no additives in -40F temps for years.
