I removed my trim today as I am swapping with another member.
The parts I was worried about removed super easy with a $15 no scratch plastic trim tool kit.
However, the door pulls, it's seems like they are designed making removal prohibitive, VERY easy to crack the whole thing.
Two of mine were damaged, each one was $70 with my CCA discount.
Not the end of the world, but something to keep in mind.
As a tip-For the left corner vent, the P3 Vent gauge DIY made that an easy removal.
