We started off with an RV5, with delux side and front panels, together with a tagalong - family of 4, although 2 kids are adult size!! Also fitted a Foxwing, with tapered sides, on the truck so the RV5 and the tagalong can be fitted to the awning. Mixture of sides and tents gives an almost fully enclosed area, with the ability to open up parts of it if needed, or fully enclose to keep the weather out.
Since then, sold the tag along and bought another RV5 - more space, still able to connect to the Foxwing and we get two stand alone tents too. (The tagalong has to be connected to another tent or the Foxwing).
Add them all together and we have some great flexibility.
Awning, connected to both tents, with the extra side and front panels gives a great base camp - loads of space for sitting, cooking etc... etc.... Even moving the truck and leaving the tents in situ is easy - as long as you mark the ground for the truck to go back exactly where it was. But be prepared for the initial set up taking a good bit more than 30 secs per tent!!!
The tent(s) pitched alone and if no extras deployed really are the 30 second tent, unless you want to put all the guy ropes up. If reasonably sheltered, guys aren't needed. Very basic is: tent up, and put 4 pegs in the ground.
The Foxwing is another quick deployment, even with putting guys on the poles - two of us can have it set up in minutes.
As you might guess, I'm sold on them. although expensive, they're well made and have stood up to some really bad weather - wind and rain - never had a leak - even when using the zippered tent connectors. As long as they're pegged down properly (as with any tent), they'll stand up to pretty much anything. Some friends of ours had some damage to their Foxwing in wind, but, if truth be known, it wasn't pegged down properly and had an open side facing the wind.
In all the years we've been camping (40+), the OzTent kit really does beat pretty much anything we've had in the past (with the exception, perhaps, of some ex military kit we have) and some of the small bivvy type survival kit.
Spares are readily available, and canvas repairs can also be easily carried out, even in the field - but that's the same for any tent if you carry the right kit.
