I'm going to need to add a winch, but the one I need is 12V.

What will I need to do to make it work with the CT battery?

Realistically, you need a small 12V battery and a 120V battery charger.
48V ports are only 400W (about a half horsepower). 12V off the trailer connector is less than that.

The one I need uses a 12v power source.

Right, so a 12V battery for peak load/ startup and either a 120V battery charger to keep it full, or connect to the 12V aux connection on the trailer 7 way to top it up (slower and depending on winch and 12V battery, might trip the overcurrent limit).

So if using winch in front, I could keep the battery in the Frunk? and recharge it with the 120v in the Cab... I wonder how long a 12v battery would last when using the winch to raise and lower a snow plow? All day?

Say a large 100Ah battery, 1.2kWh
500 pound blade, 1 foot lift = 0.2Wh, round up to 1 Wh, that's a thousand cycles.

It would be great to have up/down happen automatically with drive/reverse.

You could use a 48v-12v 100a converter with a 12v battery to handle surge. Make sure you use in line fuse the battery.

Easiest way is to just use the 48vdc in the frunk to a solar charger to a high crank 12v battery. The 48v would only act as a maintainer, but should be more than enough to keep your little 12v system in top shape for winching needs.

Solar charger (or any converter) needs to limit itself to under 400W.
Agree low duty cycle winch usage offers lower power options.

I used to sell 12V 75A server power supplies to operate RC airplane chargers. They can be run in parallel and on 240V can output 12V 100A. I put three in parallel as a test and was able to drag my wife's Y while in park and draw only 135A. My winch can draw 310A at 12V supposedly so the three in parallel plugged into the 240V output of the CT should work and draw about 30A so a 10 ga extension from the bed he front of the truck should work.
My winch is mounted on a 2" sq hitch mount so it plugs right into a hitch. Having it in the rear is great when you want to get out and not further in.
I thought I posted about it here but cannot find it.
