That's all well and good, but doesn't really counter what I've said.
Let's go back to remarkability. What you're saying is that because you can tune it, it's strong etc that it's remarkable. It isn't, really - those aspects just mean it's versatile. A Honda Civic is tunable too, and very reliable, and inexpensive to run, and even - get this - looks good, to a lot of people. Yet it's not really "remarkable".
You may scoff at this, but this truck is essentially to other trucks as the Civic is to other economy cars. Each has popularity warranted because they're good at what they do. You can draw even more parallels - if what you say is true, then the way most F-Series enthusiasts talk of trucks like this, far more favourably than they do of later ones, is just like Civic fans do of their cars...
And then to coolness. There's no correlation between coolness and whether a car is good or not, and there's no correlation between coolness and popularity.
A cool car can be good or it can be awful
A cool car can be popular or it can be unpopular
An uncool car can be good or it can be awful
An uncool car can be popular or it can be unpopular
And various combinations of the above.
What we have here - to me, at least - is an uncool car that is both good and popular. A Civic is also an uncool car that's both good and popular. The Fiat 500 from a few threads ago was a cool car (by majority vote, at least) that's both good
and popular. There are
certainly cool cars that were neither very good, nor very popular.
Of course, in your view the F-250 is both good
and popular
and cool - but there's certainly method behind those of us who don't see it that way
