I spoke to an Allstate claims representative this morning. It seems that they want to give me a whopping $1700 for my storage unit contents. However, they'll compensate up to $9k total for each item I replace. That's all well and good except it's for a storage unit so most of the contents were irreplaceable, or I don't want to replace them. (Some examples from the latter category would include an old CRT monitor and an ancient 486 PC.)
Oh, well. I guess it's nice knowing that they'll pay for the REI tent replacement.
