We hear this question all the time. The truth is the trailer owners manual is not
much good if you can find it at all. It's very generic and not
specific to your particular trailer.
Example it might say you should empty your holding tanks after every trip but it
won't tell you where the holding tanks valve is located.
It might say to empty your fresh water tank but it won't tell you exactly where
to find the drain valve.
It might say to open the low point valves when winterizing but it won't
tell you exactly where they are located.
You get the idea.
Better idea is to take pen and paper and jot down all the make, model and serial
numbers of your appliances. Refrigerator, hot water heater, stove, roof AC
and then go online to each maker web site. Most of them have a tech support area
where you can download PDF files of the owners manual for each appliance.
Then if you have other general questions about your trailer ask here.
There's a bunch of experience here just waiting to give you a hand.
