Word <em>stuff </em>is the only one that is not explained more in the sentence.
Word stuff is in general very vague word that can mean a wide array of things, physical as well as abstract. <u>We do not know what are the stuff that Sherri had in the room, what is she suppose to pack and what is scattered around.</u>
We know the word <em>her </em>refers to Sherri, the <em>trip </em>refers to her going to New York, and that <em>every </em>refers to the inches of her room.
