We do car camping at established pad sites. For the 6 of us I use 2 Big Agnes Big House 4 tents.

I've never been a big fan of the giant family tent, I prefer a couple quality tents. The BH4 fits 3 people plus gear fairly well. It has kept us dry in some heavy rains.

I have the vestibule for one of the tents. While nice it does add a large footprint.

We have only done 3 trips (2 of which had decent rain, of course) and the tents have stood up well, are fairly easy to set up, and I am happy with them.

All of my younger camping days were in a Eureka Timberline, still one of my favorite tent models.
