Because of going to campgrounds that are often a bit primitive, I've needed a good table with all four legs adjustable.
I got one from REI which is very nice 2x4, folds to 2x2 foot, quite heavy, aluminum top that dents if banged around. I really don't need something so big for just me and the dog. I can use it at home perhaps better than hauling it. I noticed on my last trip that a couple had one they never set up, but the trailer was reasonably close to their picnic table.
On Amazon, I found a Portal brand which is much lighter with an aluminum roll top. It is about 35 x 20 inches. It would be nice if a bit higher for prep or cooking, but it does work ok for using behind the galley or wherever, and all four legs adjust. The legs are held in place by a plastic piece going into notches. I'm not sure if it will last forever because of the plastic parts, but I like it, and it's easier to haul. The rest of it with legs are one folding piece, and it all goes in a bag. There is a net under the table top, attached to the legs. It's the most useful one I've found. The galley in a Five Wide gets a little crowded with no place to spread out.
