In reply to minimike:
We have an Outwell Wolf Lake 7, fekkin huge! Reason we bought such a big tent is that we have a lot of kit and we like to be very comfortable, a T5 to put it in and because its polycotton, cool in the summer, warmer in winter.
Bought it second hand as new RRP is horrendous. Extra footprint for it and the front extension means we have a 4 star hotel for all our trips. It's a big old beast but I can put it up by myself in an hour. Would also recommend a Bear Lake 6 which is what we sold to buy the WL7.
Our first tent was the Montana 6. It is by far THE most popular tent for families with good reason. Large enough, bombproof and a good second hand value. If you got one of these maybe with the front extension and of course a carpet, you'll be very happy :0)
Hope this helps, Den
