Fulltiming now in our 14th year. Sold the house and nearly everything in it. No storage desired. We thought we had it nailed, but a year later, we went through and tossed a number of other things.
Since, and to this day, we faithfully adhere to 2 rules:
1) If we haven't used it in the last year, out it goes. We haven't had to use that one in a long time because we've pared down to what we really need/use.
2) If something of lasting substance comes in, something else has to go. No exceptions. This one even saves money. :)
