It varies. Initial clean & stock after winter storage happens over a few days, though there's lots of other tasks that get done.
After initial setup and the first trip, we pull only consumables & dirty clothes, and clean the interior & sometimes the exterior.
Next trip prep - load desired clothes (ya gotta have clothes in this country even if we are naturists...) for the expected weather and activities, and consumables. Wash the rig, clean windows, touch up the interior as needed, then run a maintenance check on oils & pressures and the like.
Most shutdown activities take a half day, prep for a trip can be as short as a half day, but typically are 2-4 days ahead of the event, with perhaps 4-6 hours of actual activity spread over that time.
Day-boating prep/shutdown takes a lot less time...
