The 'owners' manual is more or less just a collection of manuals from various component mfg.
Id each of your different components....fridge, water heater, water pump, furnace, converter, A/C Unit etc.....model numbers and look for their individual service manuals.
Any kind of 'manual' for the Pilgrim will be very generic.
HERE is a Pilgrim Brochure with some information about their trailers.
HERE is a link to various mfg.
