We have always repaired on our own or had a mobile repair come in. We have never asked staff.
In a few parks the "repairman" also lived there but it was a separate business.
Sometimes parks obtain a distinct "personality". For example, some parks are known as "party parks", etc.
Maybe your park has somehow built the expectation that staff will do repairs. It will take a dedicated effort by management to change this "personality," even if they want to.
If management does not wish to change, then you will need to reconsider your continued employment there.
Hope everything works out for you.
