Friends of mine have the 6 person model they use for car camping with their 3 kids. This tent is huge and if I recall, it weighs about 25-27 lbs. So far they have not reported any issues and I have seen the tent firsthand when it has been pitched in their backyard. Quality seems decent and they have not had any leaks that I am aware of. Mind you, they also string up a large tarp over the camp area in inclement weather.
