Youtuber Simone Giertz and her friends successfully converted a Tesla sedan into a Tesla pick up truck. And she calls it "Truckla." It ends up looking pretty cool, and the process looks like they had a lot of fun. Really, I think I could hang out with these people. Haven't heard what Elon Musk thinks about it yet.
*Some NSFW Language*
And she made her own commercial for it too. Too funny!
