We bought the annex to go with your roof top tents. One for smaller and one bigger. As it wasn’t meant for the big tent with small adjustments it was perfect. We went late season (-22’C day/night) back country hunting and used 10x10 annex as mudroom/dining room. With small buddy heater it was almost as good as staying at a cabin..
I had done a lot of research before buying my tent and I'm glad I did. I picked the best to ride on my 97 fzj80. It is very tough and so simple in set up. It is impervious to the toughest rain and the thick insulated walls keep you warm and toasty. I am really impressed and would recommend this tent to anyone looking for a quality roof-top tent.
It's a great addition to a Adventure Series tent. Definitely a must have if you camp in the same spot for a few days or camp all 4 seasons. Setup takes 20ish minutes. You can probably do it in a shorter amount of time the more you setup and tear down seems faster each time. Plenty of space for gear and people.
