WordPress keeps truncating my feeds and I can’t stop it

Make sure you check the page source of your feed – some browsers will not show the full feed when looking at it raw (as the plain XML file) when using your browser to view http://yourdomain/feed

If you look at the raw source the full text should be found in under the “content” tag – Firefox for example will only show the “title” “link” and “description” but hide the content. IE will show the full feed in the browser.

Also make sure the full feed is set in the wordpress settings
