Perhaps I'm minssing something here... 

I copied one of the files anc rebuilt it for airfield_1 ... and populated it with somestatic items (I moved from the Default file).  However, it doesn't load.  What am I doing wrong :(

You need to enable the profile by running the command maprofile enable AirfieldAirwolf. Simply adding a profile data file to the oxide/data/MonumentAddons folder doesn't enable that profile. If you want to enable it without running a command, that's controlled by the oxide/data/MonumentAddons.json file.
