23ZERO Armadillo Horizon 2 Annex Room

The 23ZERO Armadillo Horizon 2 Annex Room is a fully enclosed, weather-protected living space designed exclusively for the Armadillo Horizon 2 rooftop tent, adding 67 square feet of sheltered area beneath the tent for privacy, gear staging, pet housing, meal prep, toilet use, or additional sleeping capacity. The annex attaches via keder track and zip connection and ships as a single variant.

67 Square Feet of Sheltered Camp Space

The Armadillo Horizon 2 Annex expands usable camp space from the ground up, creating an enclosed room directly beneath the rooftop tent. At 84 inches wide by 116 inches long, the floor footprint is large enough to accommodate a cot, a kennel, a portable toilet, or a full gear-staging layout without crowding. That enclosed area is protected on all sides by walls with 8-inch storm flaps, which block wind-driven rain, debris, and drafts at the base of each wall where exposure is highest.

Three Doors for Camp Flow

The Armadillo Horizon 2 Annex includes a front door (55 inches wide by 70 inches tall), two side doors (45 inches wide by 65 inches tall each), and a rig-side rear door (50 inches wide by 64 inches tall). Access points on three sides let people, pets, and gear move without bottlenecks, and each door can be opened independently to suit wind direction or site layout. Zippered flaps with integrated bug netting let each opening stay ventilated while keeping insects out.

Packs Down, Sets Up with Included Hardware

Everything needed to pitch the annex ships in the box: two telescoping poles (adjustable from 31.5 to 94.5 inches), two pole weather caps, two guy lines with tensioners, eight stakes, two cinch straps, and a storage bag for the annex itself plus a separate pole storage bag. The telescoping range accommodates the recommended 72-inch mounting height and allows some adjustment above or below that point. Packed, the annex measures 37 inches wide by 10 inches long by 11 inches tall and weighs 30 pounds.

Specifications

Who This Is For and Isn't

The Armadillo Horizon 2 Annex suits overlanders and car campers who run a 23ZERO Armadillo Horizon 2 rooftop tent and want enclosed ground-level space for changing, sleeping, pet housing, gear staging, or a private toilet area, particularly on multi-night camps where weather protection and camp organization matter.

The annex does not fit any rooftop tent other than the 23ZERO Armadillo Horizon 2; it is not a standalone shelter and cannot be pitched without a compatible Horizon tent. Mounting the tent significantly above or below the recommended 72-inch height affects annex fit: at greater heights the floor may require removal to prevent damage, and at lesser heights excess material will rest on the ground.

Common Questions

Which rooftop tent does this annex fit?

The Armadillo Horizon 2 Annex is designed exclusively for the 23ZERO Armadillo Horizon 2 rooftop tent. It attaches via the tent's keder track and zip connection and is not compatible with other 23ZERO models or third-party rooftop tents.

What is the recommended mounting height for best fit?

The Armadillo Horizon 2 Annex performs best when the tent is mounted approximately 72 inches off the ground. At heights above that, removing the annex floor may be necessary to prevent damage; at heights below it, excess annex material may rest on the ground.

What is included in the box?

The Armadillo Horizon 2 Annex ships with the annex and storage bag, two telescoping poles with a pole storage bag, two pole weather caps, two guy lines with tensioners, eight stakes, and two cinch straps. No additional hardware is required for a standard setup.

How do the telescoping poles work, and what height range do they cover?

The two included telescoping poles adjust from 31.5 inches to 94.5 inches, allowing the annex walls to be set at varying heights to match the tent's mounting position. Poles must be fully secured along with guy lines and stake-out points for the annex to perform correctly.

How is the annex stored after use?

To store the Armadillo Horizon 2 Annex, lay it flat, fold lengthwise in thirds, insert the poles, and roll tightly. Secure the roll with the included cinch straps and place it in the storage bag. If the annex is stored while damp, air it out afterward to prevent mold.
