Weber 121020 Grills

Yes, mine arrived yesterday and as John O mentioned, minor
assembly is required prior to use - affixing the handle covers
and legs , but it only takes 10 minutes.

I really do not know and guess it depends how much
charcoal you use. I only use my grill at home and not
anywhere else. Personally, I leave the grill outside overnight
to insure coals are all burned and unit is cool then clean
grill and bring it inside. Perhaps closing all the vents may
speed up cooling process but am not sure.

You can use wood chips for smoke flavor but as for actually
using wood as the heat source no. The gas and charcoal have
different internal parts that allow and protect the housing.

You dump out the ashes by flipping over the bottom half--
ideally, into a steel container where there is little risk of
embers burning the container. You can also line the bottom
of the grill with aluminum foil and just remove the foil and
ashes after it has cooled.

We use it on top of a wooden table on our deck and have not
had any issues. We bought this for camping but like it so much
that we use it at home as well.

It will fit in a popup tote, like the carrying sturdy totes for
groceries or utility tote.
