Aluminum folding camp table
small and lightweight - sets up anywhere
I call this a camp table because it's lightweight and folds up to next to nothing. It's useful anywhere though. I've taken it fishing with me and set it up beside my chair to set things on. It's surprisingly stable even on bumpy terrain and can support a considerable amount of weight. I wish I could find the specs on this thing because they're probably pretty impressive. I think I bought it at WalMart but beyond that I don't remember anything about it, although I doubt it cost much or I wouldn't have bought it.
It's become an indispensable part of my gear, primarily because it folds up to an inch and three quarters in height, meaning there's no reason not to take it. It's not big enough to serve as the main camp table, but as an extra it's ideal.
