Over the years, I have found it to be a "Law Of Nature" that "stuff" accumulates to fill all available space, plus 10%, regardless of weight.
If you clean it out in the spring, it will be full by the end of the year, leaving you wondering "Where did all this "stuff" come from?"
Some "stuff" is necessary, even though it seldom gets used. For instance, in the back country we are (used to be? I'm not sure the rule is still in effect.) required to have an axe, bucket, and shovel with us. They are still in the basement of the motorhome, and there they will stay.
