I have owned many ICE trucks over the years and I am guilty of dumping money in the trucks with upgrades and accessories . I am talking about as little as 4k and up to 12k worth of stuff on a brand new truck. I know of people that have spent way more than me. Now don't get me wrong thinking...
My guess is the back window will open if you added that option. Just like all other trucks available it is an option. And a very easy option to add.
Elon would be dropping the ball "Pun intended" if he didn't offer this option.
If you want to change the tire you will need a jack. I had a RAM truck with air suspension at all 4 corners. In order to change a tire you had to disable the air system so the truck wouldn't try to auto level the truck when you were using the jack.
Long commute and rising gas prices. Reliability and longevity of Tesla products. Total cost of ownership. Chip proof, dent proof, rust proof, bullet proof, hail proof, fade proof, scratch proof, shopping cart proof and the list goes on.
Not to mention the truck is totally awesome looking...
