Is there anything out of the ordinary i need to do with this plugin? cannot seem to get my server to recognise its even there, yet alone load, any help would be appreciated.

No, it works just like any other plugin. Oxide should detect the CraftChassis.cs file, compile the plugin, then load the plugin, which will generate the config file and register permissions. If you are not seeing this happen, it's probably an issue with your server or Oxide installation, not an issue with the plugin itself. If the Oxide file watchers are disabled are not working, you could try explicitly loading the plugin with o.load CraftChassis.
