I recently made up another of the old-school grills I had years ago. I decided that while my Weber grill was getting a bit shabby for guests it was just fine for my use. So, after buying a new one for the house, I took my trusty angle grinder with a wire wheel on it to that old, crusty one and got a remarkable amount of crud off of it. Then with the cutting blade installed I trimmed off some of the round to it to make it smaller as I figured I needed enough for 2-4 people only and a 24" or whatever they are around grill would be hard to carry in the F-250/Alaskan setup. Now it is about 16" wide and full length. Plenty of room for chow and now it fits where I want to put it. I got in the habit once of using the wire wheel to really clean it up between trips, but right now my SOP is to take a wire brush to it as soon as the steaks, burgers or whatever is off the grill and the crud doesn't become semi permanent.
I carry it out/back in a couple doubled up grocery bags which, when then get home get recycled because they are kinda nasty after using as well.
Oh yeah, you will be cutting off the "handles" which means it is now FLAT and packs easier. I usually round up a few rocks to get it to the right height over the coals and do not use that nasty "grill" the fire rings usually come with!
