I'm going to purchase a rolling duffel bag for the 3rd row footwell area, and am looking at options. Tesla has their bag: Tesla Gear Shop Trunk Rolling Duffel Does anyone have it, and would you comment on the quality, durability, function, etc? I think my preference is a bag that is a bit more subdued- solid black or blue etc. I'm curious if anyone has found a bag other than Tesla's that maximizes the space? Thanks!
