I wanna go, too!
Now don't forget a few old quilts/blankets to cushion each layer and protect the van's sidewalls on those screeching turns down the Turnpike. With all that room and that origami mind of yours you'll easily fit 60 or so vacuums, a few boxes of unsorted tools,, wands and the spaghetti String-Art of hoses on top without passing the windowsills. Clear packing tape is a great way to keep scribbled identifying post-it notes from falling off.
The major fun of sorting it all out can wait until you get home, just don't neglect to take notes and pictures, pictures, pictures.
Dave, so with you in spirit.
