Forest River has no archives for owner's manuals.
they usually only provide a generic owner's manual, that covers all types of RVs and common systems.
maybe someone has one similar in age and model to yours, that can look at theirs.
but i seriously doubt if it's worth the paper it's printed on.
you might post a similar question on other popup websites, like Popup Explorer or Popup Portal.
maybe someone there can help.
