Why I'm trying to avoid that...

My charger is connected to the exterior power port with a 3 conductor
cable (I use one for ground, and the other two for hot/neutral....in the
case of 240, I leave out neutral, and only use the L1/L2 and ground.  [3
conductor cables are inexpensive, they are called extension cords...4
conductor cables cost a lot more....]

[Yes, running a 4 conductor cable would allow me to simplify the charger
design a lot ;>]

I will make 2 cables that go from the exterior charge port to the
different outlets, but inside the truck I want the connections to remain
unchanged...
