I'm also a fan of the ALPS, though mine is called the guide table. Maybe it's bigger than the one linked above? It is big. I've had it for years. It's insanely useful, was cheap and is just plain amazing. If I had to find something to complain about it would be that it is heavy in it's case. Really sturdy.
But.....I have a pick up and tailgate camp. You will find no better tailgate picnic cover than the accordion ALPS tabletop folded out on it.
