WOW! So sorry to hear it bud, sucks to see a great truck get effed up because of somone elses carelessness.
If they total it, you can always buy it back and
1. fix it
2. part it out so it will still live! and you can get some good coin
I second the notion of going to a doctor ASAP before you speak to insurance.
They will try to pay you off with the smallest amount possible, if you feel any pain you should be rehembersed for it.
so see a doctor!
