Aside from the fact that is is pretty damn cool:
Storage
w/o winch there is a decent amount of space to cram stuff
storage for me, is always an issue
if it is tucked away, it frees up the clutter and gives me floor space
Conveniance:
kind of a table of sorts and place to put stuff because of the flat area
HiLift
good place to mount one
hope i never need to use it, but gonna carry one anyway
(hope i will never use my AED or trauma bandage either
side bar:
get the XL storage
i would get that first as it is a SMB factory item
you can always add the aluminess later
