Wet spot underneath DPF

Good morning. This is not my first 6.7L but this is the first time I've run into this "issue". I have a 2019 F450. I've had it for about 2 months now. I drove it yesterday and an hour or so after I got home I noticed a large wet spot underneath the truck. Pretty large spot on the concrete - probably 3' to 4' in diameter. It did not smell and appeared to be clear. It was just behind the cab and underneath the end of the DPF. Like I said, it had been sitting for an hour or two before I noticed it, and when I crawled underneath it there were no serious or obvious signs of leaks other than a little bit of liquid as you can see in the 3rd picture. This picture was taken even later, so the water was a little more noticeable before that but it wasn't like there was anything actually dropping.

Any thoughts on what this could be? Also when I was down there I noticed a plug on the passenger frame rail that was not plugged into anything. See picture 4. Is this how it's supposed to be?

I would say its Moisture in the system as a guess. The plug on the frame is for the lights on The Platform Style King Ranch Running Boards.

Thanks. Anything to worry about? I will keep an eye out over the next few days to see if it does it again. This was the first time I have ever seen that happen, at least to that extent.

That has happened to me in the winter. Snow, ice or slush accumulated under the truck. DPF heat turns it back to water. At least that was my conclusion, but I could be full of it.

. Have you had and recent snow or ice?

So, there wouldn't be a chance that another DPF snuck in for an overnight conjugal visit...

It was low 60s here yesterday, and I just drove it maybe 10 miles to fill up and then drove back home.

Now that I think about it, there was a Magnum next to the spill...
