OzTent RV4 Tagalong Tent?

We use an RV4 with the side & front panels and have been thinking of buying a second for the kids (girls aged 11 & 14) - they had been using our old tent which has now been put in the bin. We noticed some families appear to use 2 of these tents facing one another and connected at the awning with the side panels sealing it all off and thought we'd like to achieve that for our upcoming Ningaloo trip. I've just been checking pricing on the internet and noticed OzTent sell the "Tagalong Tent" which appears to have been designed exactly for this purpose, but it must be new, I've not noticed it before. At half the price to achieve the same goal it seems a no-brainer but I note it does not have a frame so is not a standalone tent. The only drawback I can see is if we wanted to use the 2 tents independently but I can't see that happening. If we wanted to use only 1 - we'd use the one RV4. If 2 - put them together. The sealed off centre annexe works great as a communal area and place to store pantry/food and help secure against wind etc.

Any owners out there with the Tagalong that can comment if they're happy with their purchase? It would be great to save the money but don't want to miss out something obvious I haven't thought of. I'm not sure how many more trips we'll have with both the kids so the appeal is having a great solution for 4 but without the expense. Thanks in advance.
