One other question: does the charcoal storage keep it dry enough?
My "new" SSP had cobwebs in the charcoal bin, but not a trace of water when I picked it up, and it was sitting next to a wheelbarrow with 10 cm of water standing in it. It had obviously been in the guy's yard for a while, since it was parked on bare dirt and had sunken in and gotten splashed with mud when it rained.
The design of the whole cart keeps water from having a path into the bin, as long as you don't have the lid open in the rain.
