Sorry to mislead with my subject, I already know that virtually nothing in my 2020 Expy Max is hot when the engine is off. Of course I can open a door and it lights up light a Christmas tree, the power running boards come out, the interior illumination comes on. But the various 12V power ports remain dead as the grave, as does the (mostly useless) inverter. I'd like to get my wife one of those nifty 12V car refrigerators (about 45W power draw), but it seems like a nonstarter unless I buy a spare battery for it to bounce around in the rear of the car. Is there a problem with my Expy, or did Ford design all these auxiliary power ports to be dead except when the engine is running? I own a Ram truck and a GMC truck and they both have 12V outlets that stay hot all the time....
