"Help packing your stuff/loading up..."
My dad helps me, yes. He has a truck and all I have is a little car so I sort of need him to come.
Not sure what everyone else does. All he really did was help me carry stuff though. We live about three hours away so it wasn't a big deal for him to drive up. Not sure if I answered you question, hopefully so.
We have closet doors, although a VERY VERY small minority of students do remove them. I do NOT suggest doing this, since you can break bolts or all kinds of bad, expensive things. But they all come with closet doors, yes. I drank the water all year and was fine. I used a Brita filter for the first half of the year but then I got lazy and realized it tasted just about the same from the tap.
$600 seems like quite a bit... Must have gotten some really nice fans.
It's too late now but my suggestion is to always just get the bare essentials, get those moved in, then make a walmart run while you're up there when you know what you'll have room for. Even if you forget something you can always go to walmart or kroger and pick it up.
