Tuff Stuff® Alpha II™ Clam Shell Roof Top Tent, Annex Room

The Alpha II™ roof top tent annex room* is exactly what you need for a little extra room, providing a huge space to keep your belongings, guests, kids or furry loved ones out of the elements while camping. They even include awning poles to erect overhead awning shades (using the solid door panels).

With a heavy-duty 1000D PVC floor and rain flaps to protect the zippers, your annex room will withstand wind, rain, and keep you warm at the same time.

Their annex rooms' entry door is located on the right-hand side of the annex room and includes a large zip outdoor 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 heavy winds. And there is an aluminized internal coating to retain heat.

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

*This is the annex room only, tent sold separately.

  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.

    Great product

    I barely just received it, but initial over view seems well constructed and was easy to open and close. Will have to give review when I take it out and install annex
