A group is apparently working on a trailer that can make up for some of the shortcomings of the Electric trucks. Lightship website

There is a big problem with your math.
55 amps at 400 volts is not 55 amps at 12 volts. trailers would need to operate at 400 volts in order for it to be only 55 amps.
I'm really struggling not to say...duh!!!.
Of course, the power feed from the trailer to the EV needs to operate at the same voltage to the main EV battery pack. That's why I specified it as matching.
If you want to run the house loads in the trailer, you would use an inverter that would convert the 400v DC to 120v AC (see the F150 system for an example).
There might also be a step down transformer to provide a bit of 12v power. Most EVs still maintain a small 12v battery for non-propulsion electrical needs.
