yep, no model-specific manual exists for your trailer. FR and most RV manufacturers only provide a generic owner's manual.
they're not even RV-type specific but try to cover generic systems that all RV's have in common.
you will get manuals for appliances and other similar things, like converter, radio, water pump, and so on.
if you don't have those, you should be able to download them on the manufacturer's website.
as Old Coot said, many of these are available on the library here.
