Good question! Similarly, does the second charger ever get used when the UMC is plugged into a 14-50? My car came with two chargers, but I've never charged at over 240V/40A...except at a Supercharger, which bypasses the onboard chargers.

One is a master and one is secondary. If the master is down neither will charge. The way to determine this is to check the temperature of each after an hour or more of charging. The problem is that the rear seat is very hard to get back in once removed (according to the Ranger). If you can borrow a thermal imager it shouldn't be necessary to remove the seat.

From what I have seen, my impression is that if your max amperage is set at or below 40 A then only the master is used. At 50A, it appears to use 25A/ea for master and slave. I haven't tested 41-49A.
This based on seeing the amperage rampup "stall" at the halfway point of the max amperage in the range [50,80]. My interpretation is that this stall is the wakeup+negotiation with the slave charger.
Just an impression. Could be totally wrong.
