Sliding rear cargo deck-factory or Port installed?

Does anyone know IF the sliding rear cargo deck is factory or Port installed? I have read it’s factory only? My dealer implied it can’t be added at Port but if originally allocated with sliding rear deck you can add the all weather cargo liner.

 

It’s a factory installed option.

 

Factory.

 

Thanks!

 

Sliding cargo deck, factory installed running boards and color are the only options that have to be "set" when the dealer places the order for any of the trim levels. Everything else is port installed equipment. When the dealer ordered my TRD Pro, all I needed to decide before it was built where those 3 things.

 

I believe the sunroof is also factory only.

 

Certainly! I missed than one, maybe because there was no option on my vehicle.
