I'll reply to your questions/comments in reverse order:
The guy who hit my truck was conscious after the impact, and had strength enough to climb up through the driver-side window. He must have had his seat belt on, since there was no blood visible and the truck didn't have an airbag. I'm pretty certain that he woke up with a headache, but I don't know if it was from the impact.

I still haven't seen the police report.
Once I see the report, I may decide to go for more money on the replacement value. From what I understand, the guy hit two cars earlier in the evening, so he may be maxed on his insurance limits. I'm going to borrow a bit of cash from family to buy the replacement, so I don't have to be in a hurry to reach a settlement with the insurance companies.
As for the salvage yard, $4200 sounds better, but we agreed on $3,200 and shook on it, so I'll have to stand by that.
The truck I'm buying? An '03 HO 2500 4x4 with a 6speed. The miles are higher than I'd prefer, but it's a shortbed crewcab, and it will fit in the garage, safely out of the way of (most) drunken idiots.
