How do you guys insure?

[eamims]

So I've got insurance (you have to have at least liability around here) on my '77. I've wondered what you guys do to ensure that you get properly compensated if you are in a wreck.

Let's say you have liability and someone with insurance hits you and totals your '72 pickup. Their insurance company will likely try to offer you blue book or whatever...well below its actual worth (what with all the new parts/paint/mods).

Do you guys document your truck (photos, receipts)? And does this mean anything to the big insurance companies or do they just piss on you either way?
