there is no manual with any info specific to your trailer.
nearly all RV manufacturers only supply a generic owners manual that has just basic info on common RV systems.
you can download manuals for many items in your trailer, from the manufacturers' websites.
like oven, a/c, converter, WH, furnace, fridge and so on.
