I have the Blue Tongue Off Road Deluxe and tent with extra annex.
We are a family of four with 2 young kids age 4 and 2.
We love our tent size, and how modular it is. You can set up as much, or as little as you need. We normally camp on weekends for 2-4 nights.
To setup the main section takes just over 10 mins, and we leave the annex zipped onto the main when we pack it away (we flip it over the top of the main), so setting up the annex takes an additional 10 min or so. We have set up the second annex roof as well for a super big shaded area on hot days, but haven't used the walls and the floors because we haven't needed it. I'm sure if it poured for a few days in a row, the walls and floor would be a godsend, and it's nice to know we have it if we need it.
Also, we have camped at many caravan parks including Big4s, river camps, and regular camping sites, and have never had issues fitting on a campsite or encroaching on our neighbors.
Not to steer you away from Skamper Campers as I've read that they're a great product, but there's a thread on this forum saying a couple of people who own Skamper Campers have had issues with tent leakage where the kids room attaches.
Any questions about the Blue Tongue, feel free to PM me - I would be happy to help
Cheers,
Michelle
