In reply to climber david:
Hi David, I've just got back from a car camping holiday using a Cirrus 6.
A few points.
No problems putting the tent up, expect 15/20 mins. Folding them and getting them in the bag is a bit of an art though!
The Hi Gear tents have two transverse tubes Which makes them a lot stronger and prevents water pooling on the roof.
The tent can deform ever so slightly (to a flattened semicircle) when the doors are open.
The Airtubes seem pretty robust, I was never concerned about them puncturing.
The bag is a very flimsy affair and should be better given the cost of the tent.
It fits both ways in my Mondeo estate. It is heavy and bulky.
We had two big storms, there were two small leaks, one at a door which wasn't closed properly , the other was tiny, from somewhere in the back and didn't happen in the second instance.
The guys aren't placed but despite this it stood up well to the storms.
Lots of room, stable, well made (bar the bag) - Better than the Vango and decathlon air tents IMHO.
If you have any questions PM me.
