make sure you have all your book info lined up for this truck before signing a singel piece of paper from anyone. Dumb question I use State Farm and on my old vehicles I have a set value with them since they are not restored yet hopefully yours isn't too low.
All these crashes lately makes me think we all need to call our agents and make sure everything is covered correctly. I have one policy that I called and checked on that the liability coverage was way too low(haden't been changed since 88) car and medical costs have changed a ton since then
I also think old rusty is on to something it is against the law to serve someone to that level of intoxication and the police should have some level of liability as you said they were debating the prior stop in your yard. Give them hell and good luck man.
