You also need to have the house setup to run off a generator. You don't want the truck power feeding back into the grid. IIRC, that's usually done with a big switch near the main panel.
There is a model of Ford Lightning that has power sharing and now that resale values are way down it just might be a cost effective home battery that you can drive around during non-emergencies....
You can also just plug into the 30A240V bed plug and use the onboard inverter on the lightning or powerboost hybrid f150 with less headache.
Car makers are reluctant to support this. In case of Tesla because of market segmentation.
