Kelty Gunnison 2: 4 lbs., 14 oz.
The two doors, twin vestibules make it a little heavy, but are worth it to me. I use it more for motorcycle camping than backpacking anyway.
For family car camping I have a Eureka Timberline 4 XT: 9 lbs.
We've decided, after several years, that we don't like it. The A-frame sides are claustraphobic, and the door zippers are awkward.
Somewhere I have a Slumberjack bivy shelter. It's the size of a bread loaf when packed, and weighs about 2 lbs.
