Old boater, new to cruising

[SwampNut]

I've owned a few day boats, and have piloted some cuddies for limited overnighters. We recently bought a 29' express cruiser with the intent of doing 2-3 day weekends and work up to a 1 week vacation. We are landlocked and will be primarily on lakes (some large ones, 50-60 miles long), with occasional trips to the pacific (S. CA).

I'm hoping to pick up things that the day/overnight boater wouldn't know or be concerned with. Since my family spent a lot of time in RVs when I was a child, I'm part of the way there in understanding how to live in a small space with limited resources.
