Those are literally the same truck lol. Some minor front facia differences doesn't change anything unless you're suggesting a DT bighorn is a different truck from a DT limited. Now compare a 2010 Ram vs a 2022 Ram (DT), or a 2010 GMC/Chevy vs a 2022 GMC/Chevy, or a 2010 Tundra vs a 2022 Tundra. Even Toyota who is extremely conservative when it comes to new tech, showed more life by taking a chance on some far out styling (which I personally find ugly, but hey each to their own).
The aluminium was a bit of a risk, I'll grant you that, but generally speaking they are extremely conservative with their changes, especially interior and exterior styling/tweaks.
Let's face it: the F150 is nauseatingly stale and boring at this point. And that's a choice Ford made so as not to alienate their very large customer base with changes that might not be appreciated. It's worked so far for them, but I suspect we'll see a bigger styling update next time as GM and Ram are taking sales away.
