Sorry posted this earlier in wrong forum. Not sure if this has ever been posted could not find. On keystonerv.com there is a posted list of all recalls for all their models. Its not obvious and easy to find, stumbled across it by chance. It covers off calls in USA and Canada, has the link is to the official documents.
There is also a link for a PDF version of the keystone manual. I downloaded it and will keep it on my iPad and laptop. Good backup or quick reference once in a blue moon.
