If you’ve ever woken up to sunrise creeping over the desert or felt the thrill of sleeping on top of your vehicle, you already know how rooftop tents make camping oh-so-better.
For the past eight months, I’ve been testing Roof Space’s smaller RS2 tent, and it has quickly become a favorite piece of gear. It’s easy to set up, has a comfortable mattress, and the novelty of sleeping above the ground makes every trip memorable.
When Roof Space announced a four‑person version built on the same design principles, my curiosity piqued. Is a larger hardshell rooftop tent that folds out like a soft‑shell too good to be true? Well, let’s figure it out! I break down the features that make the RS4 unique, discuss who it’s for, and sprinkle in my own experiences. By the end, you should have a clear sense of whether this tent belongs on your rig.

What Is the Roof Space 4?
The Roof Space 4 (RS4) is a hybrid rooftop tent that aims to combine the durability and ease of use of a hardshell with the roominess of a soft‑shell fold‑out tent. The tent starts as a low‑profile clam‑shell on your vehicle’s roof (only 9.4 inches tall when closed) and expands via a single flip to reveal a sleeping platform larger than a California king bed.
Roof Space calls this a “fusion” design because the tent uses a hard aluminum case for protection and aerodynamics yet unfolds to create a huge sleeping area. The result? It’s essentially giving you the best of both worlds of a hard shell and a soft shell tent.
Here are the key specifications:
| Specification | Roof Space 4 | Roof Space 2 |
| Sleeping capacity | 4–6 people (realistically fits 4 adults comfortably; includes enough room for a family and a dog) | 2–3 people |
| Mattress size | 80.7 × 78.7 in (approx. 205 × 200 cm), bigger than a California king | 80.7 × 53.1 in |
| Interior (open) dimensions | 98.4 L × 82.7 W × 51.2 H in | 98.4 L × 59 W × 51.2 H in |
| Packed (closed) dimensions | 87 L × 53.5 W × 9.4 H in | 61.5 L × 53.5 W × 9.4 H in |
| Weight | ~196 lb | ~147 lb |
| Price (MSRP) | $4,599.99 USD | $3,499 USD |
As the table shows, the RS4 is significantly larger and heavier than the RS2. That weight is a trade‑off for the extra living space and additional features. If your vehicle’s roof load limit can handle nearly 200 lb and you want a tent big enough to sleep your whole family comfortably, the RS4 demands your attention. Let’s explore why!
Setup and Design of the Roof Space 4
A Hybrid Approach
Most rooftop tents fall into one of two camps: hardshell “clam‑shell” tents that pop open quickly but offer limited floor area, and soft‑shell fold‑out tents that provide more room but take longer to deploy and are less aerodynamic on the road.
Roof Space’s engineers set out to blend these categories. When closed, the RS4 resembles a sleek wedge with aluminum sides and a robust shell that shrugs off branches and weather. Unlike traditional wedge tents where the lid lifts to create a slanted roof, the floor of the RS4 becomes the roof. This clever design allows the sleeping platform to extend on both sides of the vehicle, creating a nearly symmetrical dome inside. Because the shell forms the roof after unfolding, the tent gains 51.2 inches of headroom, which is more than many competitors.
Double‑Panorama Mode
One of the most talked‑about features is the Double Panorama Mode, an industry‑first innovation that opens both sidewalls completely. In practice, this means you can unzip and roll up the entire fabric wall on each side, transforming the interior into an open‑air cabana.
The side flaps are strong enough to act as decks, too; head out and enjoy the breeze! With both sides open, you get 270° to 360° views. As an added bonus, closing them back up takes seconds.
As someone accustomed to the RS2’s single large opening, I love the idea of creating two terraces. On our last trip with the RS2, my son and I would have loved a second deck to set up chairs to take in the view. The Roof Space 4 solves this by giving you two porches and plenty of ventilation.
Fast, One‑Person Setup
The Roof Space 2 is lightning fast to setup, as is the Roof Space 4.
Both the RS2 and RS4 boast quick deployment. It takes less than 30 seconds to set up and you can pack it away in two to three minutes. There are no complicated poles or rainflys; you unlatch the shell, push it open and secure the telescoping ladder. I’ve found the RS2 just as efficient. After eight months, muscle memory has the tent up in about 20 seconds. Knowing that the RS4 preserves this ease despite being bigger is reassuring.
Aerodynamics on the Road
A rooftop tent is only half the story; the other half is how it behaves while you’re driving.
The RS4’s 9.4‑inch profile when closed is slim compared to many soft‑shells. The aluminum shell improves aerodynamics, reduces wind noise and protects the inner fabric and bedding from weather and trail debris.
The trade‑off is weight: at nearly 200 lb, you’ll need to be mindful of your vehicle’s dynamic roof load and adjust your driving accordingly. In my experience, the RS2’s 147‑lb weight is manageable on a midsize SUV. If you drive a smaller crossover or carry bikes on the roof, the RS4 might push you over the limit.
Sleeping Space and Comfort
California King-Sized Mattress
The RS4’s party trick is its super‑king sleeping platform. The included mattress measures 80.7 × 78.7 inches—nearly square and larger than a California king bed. That surface can easily accommodate four adults, or two adults, two kids and a dog. Even though the product marketing suggests it could sleep up to six, I would caution that four is a realistic maximum for comfort. Still, if you’re used to squeezing into a typical two‑person rooftop tent, the RS4 feels palatial.
The mattress itself is nearly two inches of TPU foam topped by a nearly .5-inch anti‑condensation mat. That extra layer improves ventilation under the mattress and reduces moisture buildup, which is a common issue in rooftop tents. Roof Space also sells an optional topper for those who want an even softer bed (that’s something I appreciate on colder nights in the RS2). The mattress cover is washable, and there’s enough room in the folded tent to store bedding inside. This is also a feature I’ve found invaluable, especially when packing up in the rain.
Headroom and Layout
With 51.2 inches of headroom throughout, the RS4 allows adults to sit upright anywhere in the tent. In contrast, many clam-shell tents taper at the foot end. The symmetrical design means you don’t have a “tall” and “short” end; whichever way you orient yourself, there’s ample space for pillows and gear. At the head and foot of the bed, there’s an extra cavity for storing clothing or small duffels so they don’t encroach on sleeping space. Zippered pockets and a mesh gear loft provide additional organization.
Views and Ventilation
The double‑panorama openings are lined with mosquito netting attached via double zippers. This allows you to enjoy a cross‑breeze without inviting insects inside. There are also windows at the front and rear of the tent for peekaboo views and ventilation.
In the RS2, we often open the side wall to watch the stars; the RS4’s ability to open both sides means you can catch sunrise and sunset from the comfort of your bed. If you’re camped in a scenic spot, that alone is worth the price of admission.
Materials and Durability
Fabric and Waterproofing
Roof Space uses a 100 % polyester ripstop fabric rated at 280 g/m² with a 3,000 mm water‑column rating and PU‑taped seams. That means the tent can handle heavy rain without leaking, and the ripstop prevents tears from spreading. The fabric also has a pigment coating for blackout and UV 50+ protection, which helps keep the interior dark for sleeping past sunrise. In my experience with the RS2, I’ve camped through downpours and gusty winds without any leaks or flapping. The RS4 uses the same material, so I expect similar performance.
The RS4 is marketed as fully dust and waterproof thanks to its patented seal design. While “dustproof” claims are always relative (fine silt can infiltrate anything), the RS2 has kept the Nevada dust at bay better than other tents I’ve tried. The edge seal compresses evenly when closed, and the latches pull the shell tight to minimize gaps. If you frequently drive on dirt roads or through deserts, this feature becomes critical for protecting your bedding and electronics.
Shell and Hinge System
The aluminum hard shell provides structure and protects the fabric when closed. The hinge hardware feels solid, and the mechanism has been reinforced compared to the RS2. Many hardshell tents rely on gas struts to push them open; Roof Space uses spring steel rods in the wall panels and a robust hinge system for the floor/roof flip. This design allows you to open both sides symmetrically without extra poles. As always, check the mounting hardware on your vehicle regularly; any rooftop tent is only as secure as its crossbars.
Features That Stand Out About the Roof Space 4
Quick‑Release Ladder
Included with the tent is a telescoping ladder that attaches via a quick‑release system. It extends to 102 inches, which is long enough for tall trucks and vans. The ladder can be mounted on either side of the tent. When you’re using the double‑panorama mode, this flexibility helps you access whichever deck you’re using as an entrance. In my RS2, the ladder is sturdy and easy to retract; I expect the same design in the RS4.
LED Lighting and Accessories
Inside the tent is a built‑in dimmable LED light (battery not included). This might sound like a small feature, but integrated lighting eliminates the need to string up lanterns or headlamps. The RS4 also includes pockets for phones and small gear, spring steel rods for awnings, and a cinch bag for storing the ladder and stakes. If you’re like me and often forget to pack away small bits when breaking camp, having dedicated storage in the tent itself is convenient.
Additional Storage and Bedding Space
Despite the slim profile of the RS2, I can leave my bedding inside. The same is true of the RS4.
One of my favorite aspects of the RS2 is the ability to leave bedding inside when you close the tent. The RS4 takes this further: there’s enough room to stow bedding for four people plus a few pillows when folding the tent. That means you don’t need to haul blankets into the cab or under a tonneau cover every morning. After long days on the road, the fewer steps between you and sleep, the better!
LED Windows and Privacy
The tent’s windows are designed to maximize views but can be zipped closed for privacy. A small peak window near the head offers ventilation while keeping rain out. You can also partially open the sidewalls while leaving the mosquito net zipped, which keeps the interior airy without leaving it exposed. For families, that ability to adjust ventilation and light quickly is essential; kids can nap while adults hang out outside.
Ease of Use and Practicality
Setup and Takedown
The RS4 can be set up by one person in around 30 seconds. When I first tried the RS2, I was skeptical of the marketing claim, but it proved true: unlatch, push, secure the ladder, and you’re done. The RS4’s extra weight doesn’t slow the process; the hinge mechanism and gas struts do most of the work. Tear‑down takes slightly longer because you need to tuck in the fabric, but it’s still under five minutes. That speed makes day‑to‑day travel far more pleasant because you can set up camp late or leave early without drama.
Weight and Vehicle Considerations
The elephant in the room is the 196‑lb weight. That’s heavier than some competitors like the Roofnest Condor 2 XL (180 lb) and iKamper Skycamp 3.0 (165 lb). The extra 30–40 lb may not sound like much, but it affects your vehicle’s roof load rating and handling.
Roof Space recommends a minimum dynamic roof load of 198 lbs; you’ll need robust crossbars or a platform rack. I would avoid mounting the RS4 on smaller crossovers or cars and instead pair it with SUVs, trucks, or vans with strong roof systems. If weight is a deal‑breaker, the RS2 or other lighter hardshells might be better suited for your rig.
Fuel Economy and Wind Noise
Roof Space 2
On long road trips with the RS2, I’ve noticed a modest drop in fuel economy—roughly one to two miles per gallon. The RS4 is bigger and heavier, so expect a similar or slightly greater impact. However, the low profile and aerodynamic shell help. Compared to boxy soft‑shell tents with vinyl covers, the RS4 should be quieter on the highway and less susceptible to crosswinds.
Ladder Placement and Vehicle Height
Because the tent opens on both sides, you can choose which side to mount the ladder depending on your campsite. This can be helpful if you park next to a cliff edge or tree. For tall trucks, ensure the ladder is fully extended; the quick‑release system prevents the ladder from slipping, but double-check the connection each time.
Weather Protection and Four‑Season Use
Insulation and Condensation Management
The RS4’s fabric is thick enough to provide some insulation, and the anti‑condensation mat under the mattress helps mitigate moisture buildup. In my RS2, condensation is minimal even in cold weather, provided I crack open a window for airflow. Adding Roof Space’s optional anti‑condensation pad or a third‑party insulation liner can further improve winter performance. For summer camping, the large mesh windows create cross‑ventilation to keep the interior from turning into a sauna.
Rain and Wind
With a 3,000 mm water‑column rating and taped seams, the RS4 is designed for heavy rain. The hard shell acts like an umbrella over the fabric, and the rain skirt prevents water from seeping under the edges. In strong winds, the RS2 holds up well due to its low profile; the RS4’s broader footprint may catch more wind, but its robust shell should keep it stable. Always secure the ladder and guy lines if conditions look rough.
Snow Load
The RS4 is not marketed as a heavy‑snow tent, but the hardshell top can support some accumulation. If you plan to use it in winter, clear snow off periodically to avoid overloading the hinges. The double‑panorama openings can be zipped closed to retain heat, and an insulating sleeping bag will do the rest. For extended winter expeditions, a hard‑walled camper or four‑season ground tent might be more appropriate.
Comparing the Roof Space 4 to the Competition
iKamper Skycamp 3.0 and Roofnest Condor 2 XL
The rooftop tent market has exploded in recent years, with brands like iKamper and Roofnest dominating with their fold‑out hardshell designs. The iKamper Skycamp 3.0 (shown above) sleeps four and weighs 165 lbs, while the Roofnest Condor 2 XL offers a similar footprint and weighs 180 lbs. Both use a traditional lid‑over‑floor design: the hard shell opens to reveal a fold‑out platform. They are slightly lighter than the RS4 and cost around $4,200–$4,500, comparable to the RS4’s price.
What sets the RS4 apart is the symmetrical flip design where the floor becomes the roof, creating more headroom (51.2 in vs. 49 in or less) and enabling the Double Panorama Mode. The RS4’s sleeping surface (44.1 square feet) is only marginally larger than that of the Skycamp 3.0 (around 44 square feet). The difference may be negligible on paper, but the RS4’s ability to open both sides and create decks provides a more versatile campsite. The trade‑offs are weight and complexity; you must decide if those features justify carrying an extra 15–30 lb.
Soft‑Shell Fold‑Out Tents
Soft‑shell tents like the Tepui Explorer Autana or CVT Mt. Rainier offer massive sleeping space and annex rooms, often at lower prices ($2,000–$3,500). However, they use fabric covers and multiple poles, which means slower setup and poorer aerodynamics. After living with the RS2, I can’t imagine going back to a soft‑shell that takes ten minutes to deploy. If you value speed and protection, the RS4 is worth the premium.
Price and Value of the Roof Space 4
At $4,599.99 MSRP with occasional preorder discounts around 10 % (about $4,140), the RS4 is an investment, to say the least. But, for that price, you receive:
- The tent and case
- A 5 cm foam mattress with 1 cm anti‑condensation mat
- Anti‑condensation mesh under the mattress
- Telescoping ladder with quick‑release mounting
- Mounting brackets and hardware for roof racks
- Spring steel rods for awnings and cinch bag for storage
Compared to buying a hardshell tent plus annex or decking system separately, the RS4 offers value by combining those features into one package. However, if you never plan to use the double‑panorama decks or don’t need to sleep more than three people, the RS2 or other lighter tents may provide better value. Also consider that the RS4’s weight might necessitate a heavier‑duty roof rack, which adds cost.
Who Is the Roof Space 4 For?
After poring over specs and reviews, I see the RS4 as ideal for families and groups who prioritize comfort, views and quick setup. If you’re a couple who loves the RS2 but need more space for kids or pets, the RS4 is the natural upgrade. If you’re a solo traveler or duo who values weight savings and only occasionally hosts guests, the RS2 remains excellent.
Off‑road enthusiasts with trucks or 4×4 vans will appreciate the RS4’s durability and ability to leave bedding inside. Van‑lifers may prefer roof‑mount options that allow full access to their interior; the RS4 needs external access via ladder.
One thing I appreciate as someone who has used the RS2 extensively is how Roof Space listens to customer feedback. The RS4 addresses many minor complaints about the RS2: more storage space, improved mattress, reinforced hinges and the ability to open both sides. It feels like a product designed by people who actually camp in their tents.
Practical Tips and Final Thoughts
Check your roof load. Before buying, verify your vehicle’s dynamic and static roof load. You’ll need about 200 lb dynamic capacity, plus extra for racks and accessories. Static loads (when parked) are usually higher, so sleeping four people shouldn’t be an issue.
Consider installation. At nearly 200 lb, installing the Roof Space 4 requires at least two strong people or a hoist. Once mounted, you probably won’t want to remove it often. Make sure to torque the mounting bolts properly and recheck them after your first trip.
Plan your bedding. Take advantage of the storage space by leaving sleeping bags and pillows inside. If you camp in cold climates, consider an insulation layer or additional mattress topper.
Use the decks. Don’t forget the double‑panorama decks! Bring a couple of lightweight chairs or a small table and enjoy an elevated patio. Many photos show people fishing, cooking or stargazing from the side flaps; that’s not just marketing hype—the platforms are sturdy enough to support moderate weight.
Think long term. Rooftop tents hold their value if well cared for. A high‑quality tent like the RS4 can last many years and can be transferred to different vehicles. While the price is steep, it’s comparable to the cost of a used teardrop trailer, and the flexibility to mount it on various rigs is valuable. For families that camp frequently, the RS4 could replace the need for a trailer altogether.
Personal Verdict
Roof Space 2
Reflecting on my eight months with the RS2, I’ve come to appreciate how a rooftop tent changes the rhythm of travel. The RS4 promises all the things I love about the RS2—speed, comfort, durability—but scales them up for a family.
The ability to wake up to a 360° view on a cliff edge or to read a book on a built‑in deck while listening to the rain is pure magic, too. Yes, the tent is heavy and expensive, but if you value time and quality of experience more than the hassle of setup and pack‑down, the RS4 may be worth every penny.
In the end, the Roof Space 4 is a well‑engineered, feature‑rich rooftop tent that pushes the boundaries of what a hardshell design can offer. Its super‑king sleeping area, double‑panorama decks and quick setup make it stand out in a crowded market.
For folks seeking a comfortable and unique basecamp for family adventures, the Roof Space 4 leaves little to be desired. Your only question should be: do you have a vehicle worthy of this rooftop palace?
