I've got an Oztrail Sportiva Peninsular which has a "4x4 docking bay". I think most (not all) of the 'Sportiva' range has a docking bay, except the 'Commune's'. Mine sleeps 9-12 in 3-4 rooms, but they do have smaller/cheaper ones as well with the docking bay. Check their website
www.oztrail.com.au for the specs (the site is actually down at the moment). I paid $429 + $10 shipping online from
https://www.tentworld.com.au, which is $50-$70 cheaper than anywhere else. You cant beat $10 for shipping on a 33kg tent!
