When "WE" are leaving our Redwood unattended we do the following:
~turn water OFF and disconnect the hose from the wet bay.. This way there is NO chance a valve goes bad and the coach fills with water.
~put all slides IN
~close all sewer valves
~turn OFF HVAC and water heater
~make sure the Surge protector is in use
There may be more, but that's a short list off the top of my head
