These look top quality! Thanks for sharing.
My dog is in the cargo area of the car, it's great, and allows for other passengers. I like the cargo area mostly because the floors are flat there's much more room than backseats.
1. Tesmanian floor mat (it even folds so we can access the under floor area)
2. Tesmanian second row back (it keeps the backs clean, looks really OEM especially matching the floor mat)
3. VarioBarrier HR small (crash tested, keeps dogs from flying through the car in the event of a head on). I don't even need the top piece. Looks great.
What I want is to get the wheel tops covered too, it's the last area that's still "felt" in the back. While it keeps fairly clean, the dog hair that collects on it is just insane. In my Subaru Outback, we got a few pieces from Canvasback that fit perfectly, hopefully they'll have a Model Y custom soon.
EDIT: OMG they actually have it made already for the MY. They have the full liner:
Tesla Model Y Cargo Liner
It's in multiple pieces so you can get to both under storage areas, but probably won't catch any spilled stuff.
I'm definitely adding to my setup with:
Tesla Model Y Back Hatch
Tesla Model Y Cargo Side Pieces
