Lovely tent but, sorry I haven't got one, so I can't help. I've got an elderly Robens LemonGrey which is a super tent, but it's got two little porches instead of the one large porch on the Fortress. Can't fault the quality though.
Anyway, I've bumped your post back up to the top, so hopefully someone else may be able to help you
Tell me about it!! I looked long and hard for info and reviews of the Fortress. In the end I went to the Cotswold Tent show in Betys y cowed. Aperfect excuse for a weekend away he he.
