I really, REALLY like the idea of seperate cabs and beds.
A "raw body kit" of sorts.
Offer a cab for "popular truck X"
Make a standard or 4 door cab.
Then make a long or short bed.
Show off the flexibility of the ascender 2- I mean scx10 III with the adjustable wheelbase!
Or if thats too difficult... Make a jeep that looks just like the new bronco!

And while youre at it maybe follow jatos advice and make the f150. Not because I daily drive a 2019... But because they are awesome.

(mine is a 4 door short bed STX. You know... For reference)
So those are my answers:
Current license - multiple wheelbase separate cab/bed combos
"Wish license": - go hard at ford and give proline and traxxas some competition!
Wait doesnt horizon have a ford license?
Thinking of the orange ascender f100 BND...
