The Outwell Montana 6 is a superb tent, you can comfortably fit 6 people into it, although we mainly use it for 2 adults, 1 child and 2 dogs. it is very waterproof, following 2 weeks of British Summertime rain, it wasn't until the 13th day that we got any water in and that was only when the wind flicked the roof up and a couple of droplets came through, nothing got wet.
I recommend watching the video as to how to put the tent up, the first time it took us just over an hour, but now, my husband can put it up on his own (with me just holding one guiderope) in 30 minutes.
You can take everything, even the kitchen sink, when camping in this tent. We use the side porch for storing alcoholic beverages and have the canopy extention on the front, which provides shade from the sun for our daughter when she is sat outside eating.
There are lots of pockets on the outside of the bedrooms which are really handy for storing things. The tent is all enclosed, so not escaping children or dogs under the bottoms of the tent like we had with our old one... nor floods of water going straight through after torrential rain overnight.
The only bad thing I can say about this tent is the weight, it is very heavy at just under 34kg, but, that is what husbands are for!
