I like my truck the way it is. What I'm modding is to make it mine (appearance items) & make it better suited for my needs (functional items), not to make it something other than a Super Duty Tremor.
But if the Ranger and F-150 set a Tremor trim level standard for added Tremor content that then migrates to the Super Duty prior to whenever the next all new Super Duty is launched, that would kinda suck. Like if they add "TREMOR" stitching in the seatback for 2022, but 2022 isn't an all new Super Duty, I guess I might be chasing down the new upholstery and be miffed about it. Or a steering wheel center indicator. Or 7.3L badging. But I'll be handling my own exterior stripes. And it's not gonna look like that.
If any new SD Tremor content waits for the introduction of an ALL NEW Super Duty, then so be it. Newer and improved'er is a fact of life like taxes and dying.
As for the spread of the Tremor trim line, I've said my peace before. Short version: I see name recognition as a positive, increased awareness of a higher level of factory off-road readiness (above FX4) is a good thing for value.
