I'm running a KM game and we recently started up book 2 and the kingdom building that goes along with it.

This sheet is fantastic and covers just about everything that you could possibly need. That being said, it utilizes the Ultimate Campaign ruleset as opposed to those described in the KM books themselves, but many believe this to be much for the better.

There's another one the author is working on that will include the Ultimate Rulership rules as well. Here's a link to a post with links to the excel/open office versions of both sheets.
