2019 f150 stx

SOS! I tried to disable the PowerPoint timeout on my 2019 F150 because I’m a First Responder and need the plug to remain hot with out the truck running. I’ve tried everything that I’ve found on the web, including the Forescan worksheet and it still turns off when I cut the engine off. please...

I found two 2019 F150 I liked, same price range $35K one has 24,000 miles came from commercial and private leasing, not regular oil changes and not at a dealer, second has 40,000 miles, one lease and regular at dealer oil changes intervals. Any help choosing will be appreciated! Thanks.
