Is there a frunk or a floor hatch in the back where I can keep a 50 foot extension cord?

No and no if you look at the body the back does not have much depth and there's not enough room in the front for a frunk they said

My current BEV has no frunk or floor hatch, so I keep my 50' 14-gauge extension under a front seat.

Lance, is that Jerome, AZ? There is a "back pack" behind the seats that might hold a cord. We are just starting to see some of the interior features and they are still evolving. Back in the late 80s I worked at Mingus Mountain High school for Jerome Instrument

Yes, Arizona. I know about Jerome Instrument. I know we'll have to get the the front of the car someplace to service the brake master cylinder reservoir? and fill the windshield washer bottle? If the front lid opens somehow, maybe I can snake an extension cord around in there. It wouldn't take much volume really and is pretty formable. Even if its not supposed to be a frunk.

I don't know the answer yet. What a beautiful part of the world you live in!
