In reply to stuartgmilton:
I've got a Tempest 300. It's fine for car camping and sea kayak camping. You wouldn't want to carry it far on your back though. Enough room inside for two adults and a kid. You wouldn't get three adults sleeping in it unless you had co-ordinated rolling over in your sleep. We use light thermarest style mats.
You can cook in the porch but there isn't much room. Nobody could get past you if you were cooking in there. The outer door rolls to the side so you can't put poles under it to have a more covered entrance.
It's a good tent though, no leaks, easy to put up on your own and it's survived some fairly windy nights. I've had mine a few years now. I got it cheap because it was the previous year's model (!).
