What is this part called?

Long story short, I brought my truck in to install a Stinger HEIGH10. When I picked it up, there was damage the the passenger side plastic behind the plastic door sill (see photos - the smooth portion behind the front portion with the grip on top). Apparently they had to take out my seat to install my system and I’m guessing they scratched up the plastic when taking the seat out or putting it back in. I will bring it back tomorrow and hope they compensate me for the damages. But I’m curious - what is it called and does anyone know the serial number?

Also, is it easy to replace, or does it requiring removing several other parts to remove?

Pretty sure its called the threshold trim. Not difficult to remove, but it is long. Extends from the foot kick panel, to just behind the front seat.

It's just clipped in place, but you'll want to use plastic trim tools to remove it.
