Another one bites the dust

Before you try to sell the SCT tuner you need to unlock it from your truck. You need to return your truck to stock which will then unlock the tuner. If the battery is ruined just hook a battery or a jump box up to it temporarily and do what ever you need to do. If you don't unlock it you will have to send the tuner back to SCT and have it unlocked by them.

The frames on these things bend kinda generously in wrecks. In a direct (not offset) head-on the frame usually bends downward at about the back of the cab, in offset head-ons they usually bend sideways away from the impacted side and downward at the same point. Pretty typical damage there, from the look of it.

The box didn't shift, he hit about half head on, so the whole cab turned counter clockwise to the frame. If you look at the picture of the left side, you can see the right front tire is now sitting entirely out of the fender with the rotation.
