Owners manual

I have whole suitcase of manuals from 2002 Lance that I parted. All appliances are the same stuff via many years.
Pay shipping and its yours.

What information are you looking for?
I can't speak for Shadow Cruiser, but typically the manuals are very generic.
If there is a problem with any of the appliances or another technical component, the manufacturer's manual for that component will be more detailed. You need to find out the manufacturer and model of the appliance/component; most manuals are available on the net.
Here is a Link to the Lance manual page which goes back to 1993; it may or may not provide some generic insights:
