Rooftop Tent Annex Rooms: When You Need One

What an annex room is

An annex room is an enclosed space that attaches to the side of a rooftop tent, usually at ground level. It extends the footprint of the tent past the roof of the vehicle, giving you room to stand, change, store gear, or set up a cot. The term appears on rooftop tent listings as "annex", "annex room" or "room enclosure". Overland Vehicle Systems, for example, lists an "Annex Room Enclosure for XD Sherpa Hybrid Rooftop Tent" on its pages, which shows how the word reads in a maker's catalogue.

The same maker describes its HD Nomadic 3 annex as having a PVC floor and mesh screen doors and windows. That combination tells you the annex is designed to keep ground moisture away from the sleeping area and let air move through while you change or store gear. The maker's listing is the source for what a specific annex includes, so read it before you decide.

• A place to change out of outdoor clothes without doing it in the sleeping area.
• Storage for boots, coolers, chairs and bags that would otherwise crowd the tent.
• Extra sleeping space for a child, a pet, or a second adult, depending on the size.

How an annex room attaches and works

An annex attaches to the tent through a zipper, a sleeve, or a connection panel that the maker designs for the matching tent model. The Overland Vehicle Systems listing shows the annex as a separate piece made for the XD Sherpa hybrid rooftop tent, which means the annex and the tent are designed to work together. A hybrid shell opens with a fold-out section, and the annex extends that space down to the ground. If you are comparing hybrid designs, the connection is part of what the shell makes possible.

Because the connection depends on the specific tent, the maker's product page and instructions decide whether an annex fits your model. If a listing says the annex is made for the XD Sherpa, it is not a general-purpose accessory. Compare listings by reading whether the annex names the same tent as yours. The same rule applies to a soft shell versus a hybrid: the shell shape tells you whether a matching annex is likely.

Which shells offer an annex room

Annexes show up most often on hybrid and soft shell tents, because those shells have fabric sections that fold out and can meet the annex's connection panel. Hard shell tents are rigid and usually do not have a matching annex listed; their weatherproof case is the shell itself, and a separate awning with walls may serve a similar purpose. The Overland Vehicle Systems pages include an "Awning Attachment for XD Sherpa Hybrid Rooftop Tent" and awning walls, so you can see how a maker offers both an enclosed annex and an open awning for the same tent.

On a listing, the shell name tells you which group to look in. A hybrid title often reads like "hybrid rooftop tent" or names the model, such as XD Sherpa. A soft shell title may state the fabric type. If the shell is not stated, ask the maker before assuming an annex exists. The soft shell guide and hard shell guide compare the stated details for each group.

When you need an annex room

You need an annex when the trip includes ground-level activities. Families with small children often use the annex as a changing and nap space while the rooftop tent stays closed. Longer trips benefit because boots and food bags can live on the ground instead of on the mattress. A couple who wants to sleep in the tent and have a private room for dressing finds an annex useful. The 4 person tent guide covers options that leave room for the whole family.

You can skip it when you are a solo traveler who changes inside the tent, when you camp for one or two nights, or when the trip is mostly driving and sleeping. An annex adds a separate piece to pack and set up. The National Park Service camping pages describe planning for a full camping experience, and an annex is one way to plan for more comfort, but it is not required for a simple night under the stars. The rooftop tent guide is a good starting point for a first purchase without extras.

What to read on a listing

When you compare rooftop tents, read the title and the bullet list for the word "annex". A listing that includes an annex will usually say so, either as a bundle or as a separate item. The Overland Vehicle Systems listing prices the annex separately from the tent, so you can see the two as distinct purchases.

This site's comparison is limited to stated details, so the same rule applies here: only read what the listing says, and ask the maker about anything that is not written. A missing detail, like no floor stated, means you should ask the seller what the annex includes.

• Floor: does the annex include a PVC floor, or do you need a separate ground sheet?
• Mesh and windows: do the doors and windows close with mesh for airflow and windows for weather?
• Match: does the title name the tent model the annex fits, such as XD Sherpa?
• Shell: does the annex belong to a hybrid, soft shell, or hard shell tent?

Questions to ask the maker before you buy

Ask the maker whether the annex fits your tent model and whether the floor, poles and stakes are included. Ask how the annex connects and what the maker's instructions say about the connection. If your vehicle, rack or crossbar takes part in attaching the tent, the maker's instructions and your vehicle manual decide those steps, so make those questions part of your list.

Ask about returns and spare parts in case the annex arrives with a damaged zipper or torn mesh. Keep the original packaging and photos of the box before you set it up. The maker's contact page is the place to ask, and the Overland Vehicle Systems guide shows how a maker's lineup reads on one page.

Questions

What is an annex room for a rooftop tent?

An annex room is an enclosed space that attaches to the side of a rooftop tent at ground level. You can use it to change, store gear, or set up an extra sleeping spot.

Do I need an annex with a hard shell tent?

Hard shell tents usually do not list a matching annex because the shell is rigid. A separate awning with walls can serve a similar purpose, so read the maker's listings for the tent you are considering.

Can I sleep in the annex room?

Depending on the size, an annex can hold a cot or pad for a child or an adult. The maker's stated dimensions and the floor area tell you how much space you actually get.

Does the annex room come with a floor?

Some do. The Overland Vehicle Systems HD Nomadic 3 annex is described with a PVC floor and mesh screen doors and windows. Others may not include a floor, so read the listing before you buy.

How do I know which annex fits my tent?

The maker names the model the annex is made for, such as the XD Sherpa. If a listing does not name the model, ask the maker directly.
