The 2020 F-150 had a turning radius of up to 26.5’. For comparison, a Toyota Camry can accomplish the feat in about 19’.
I test drove a 2020 F-150 SuperCrew and did a quick turning radius test to see how it would do. While not as bad as I expected, you can definitely tell it needs some room to turn around without doing a three point turn. The 2021 F-150’s overall track/stance is 3/4” wider than the outgoing model, so that will probably take more turning radius distance as well.
