I'm trying to a sense of how much storage there is in the back trunk of a Model Y with the 3rd row up. Online I only see 'max storage' which includes frunk and the space with both 2nd and 3rd row folded down. Can someone that owns a the 3 row configuration please measure and post the size of the useable trunk space? Better yet, if you can compare to a Model 3 trunk/frunk space for reference that would be great.
