I've seen Andy in competition. He's not hauling that truck all that way to lay down. The race was lost at the line. Andy slept. As far as Casper, the truck isn't sorted out yet.
Sleeping on the tree doesn't explain the ET being a full second off of his "shakedown" pass, and the disappearing 10 mph. Watch the video. He clear as day rolls out super easy, and didn't even get into it till half track.
