Tuff Stuff® Alpha II™ Clam Shell RTT, Annex Room

The Alpha II™ Roof Top tent annex room is truly, the "Alpha" of all annex rooms, providing a huge space to keep your belongings, guests, kids or furry loved ones out of the elements while camping.

With a heavy-duty 1000D PVC floor and solid panels to protect the zippers, your annex room will keep you and your gear sheltered and out of the elements.

Our annex rooms' entry door is located on the front side of the annex room and includes a large zip out door at the rear wall to access your vehicle's passenger doors or bed while setting up at camp. NO-SEE-UM mesh screens have been added at all 3 windows including the entry door so you can still enjoy the beauty of the outdoors.

Guide ropes are included for increased strength in breezy conditions. And there is an aluminized internal coating to better retain heat.

This is a must-have addition to your Alpha II™ Hard Shell Roof Top Tent!

  1. Zip the PVC floor onto the side walls.
  2. Spread out the floor until it is flat and locate the upper zipper. The annex walls zip on at the perimeter of the tent's overhang.
  3. Make sure your floor is evenly spread out. Use stakes to tie down the floor at the appropriate loops sewn into the annex room walls.

*Be sure to spread out the walls as tight as possible to ensure no moisture collects in low spots, causing pooling. Over-saturation will cause water to eventually penetrate the fabric after heavy rainfall over several hours. NOT recommended for high winds/heavy rains.


Q & A

What is the annex room made from?
Manufactured from high-quality polyester/cotton windproof fabric.

Can I have the access door from any side of the vehicle?
Technically, no, the Alpha tent can fold open only from the passenger side of the vehicle, therefore the annex room will only have access to the passenger side of the vehicle.

Do I need an Annex Room?
Yes, you're going to want to spread out. Having extra storage and space when you need it most is what an annex room is all about. Put those kids and pets down below while you enjoy the scenery from above. And why not? You've worked hard to get here! Also, the Annex Room makes a great changing room instead of having to climb upstairs to switch out of the bathing suit and into camp wear gear... e.g. Ugg Boots and a sweatshirt.
