Bronco's don't have pickup beds. Who died and made this a Bronco forum. Besides, I just got rid of a 2024 Silverado I owned 3 months for a used 2021 Gladiator. I could not be happier. I am sure the Brono forums are full of complaints too.
Depends on you and your situation. Both seem like decent deals. Buy the more equipped one with some miles, and let the previous owner pay for the extras, and lack warranty except any remaining. Or spring for less equipped new, no mileage, and full warranty. The price difference is not a small...
