Cuisinart CCG-100 Gratelifter Portable Charcoal Grill

I don't know the weight but it has clasps to hold lid on tight
during transport.

That's your choice. If you don't want it sitting down low in the
sand, you need it up higher. A tabletop would be fine. But it
should be a non flammable surface.

Yes the grill removes very easily from the base for
transportation. We have had our for a couple of years now and
just love it!

I'm pretty sure they do make a cover for it.

No, they do not fold. we bought a stand for the grill and sat it
on our deck.

You can close the lid if the grate is lifted, when you shut the lid
you can slide a button on both sides to lower the grate for
cooking.

It doesn't remove as easily as one sitting flat, but it's not too
cumbersome either. We are using it again this Labor Day
weekend and love it. Ours is charcoal.
