Supertramp Campers built its reputation on high-quality, carbon-fiber shell, pop-up truck campers. The brand’s original designed challenged the RV industry’s focus on comparably cheap materials. Now, Colorado-based Supertramp expands into the hard-sided camper market with the Flagship HT, a lightweight, insulated design for full-size trucks.
This marks Supertramp’s first entry into the hard-side segment, following the success of its LT pop-up model. The Flagship HT retains the company’s signature one-piece carbon-fiber composite construction, which looks like it will deliver superior insulation and durability without the bulk of traditional truck campers.
Keith Panich, owner and lead engineer at Supertramp, said the transition to a hard-sided model was a natural fit.
“The Flagship mold was designed from the beginning to serve for multiple styles of slide-in camper solutions,” he said. “The base is the same, but it feels like a completely different product on the inside.”

Supertramp Flagship HT Hard-Side Camper
Supertramp builds the Flagship HT using a fully composite, vacuum-infused shell, eliminating aluminum and wood framing. The camper has 2-inch composite walls that extend to the roof, designed to enhance structural integrity and insulation.
With 1.5 inches of insulation vacuum-infused into the walls, this design caters to true four-season capability. The materials also promise durability and sound damping, both attributes suitable for a noisy parking lot at your local ski hill.
Despite moving to a hard-sided design, Supertramp claims the Flagship HT is only about 50 pounds heavier than the LT. The camper’s dry weight falls between 1,399 and 1,750 pounds, depending on configuration. While the solid walls add weight, the HT saves pounds by eliminating the lifting mechanisms required for a pop-up design.
Many comparable four-season truck campers weigh significantly more, making the HT a strong contender for those who want a fully insulated, hard-sided camper without maxing out their truck’s payload.
This weight range makes the HT a realistic option for half-ton trucks, not just three-quarter-ton and one-ton trucks like the Ram 2500, Ford F-350, or similar heavy-duty pickups.
If I could have my ideal setup, I’d pair it with an AEV Prospector XL built on a Ram 3500 chassis. That combination would leave the truck largely unstressed while providing all the off-road modifications needed for true backcountry travel straight from the factory.
More Views, Ventilation, Comfort
Unlike many hard-sided campers that feel cramped, the Flagship HT prioritizes natural light and airflow. It has six Arctic Tern dual-pane acrylic windows, along with an additional window in the entry door. These windows provide panoramic views while maintaining insulation and ventilation, which should help keep the interior comfortable in extreme temperatures.
“360-degree views is our thing,” Panich said. “A lot of hard-side campers feel cramped and cluttered on the inside, and we wanted to keep things open and airy.”
Spacious Interior, Smart Storage
Inside, the Flagship HT aims for a balance of comfort and functionality — in a small space. The L-shaped couch creates a dedicated space for dining, working remotely, or relaxing after a long day on the road.
Under-seat storage maximizes space, while optional Molle gear walls and L-track storage keep essential items within reach.
Supertramp designed the Flagship HT with an east/west queen bed as standard. However, for those who prefer a north/south sleeping arrangement, an optional folding extension expands the bed into a king-size layout.
This setup provides more flexibility and a larger sleeping area without adding to the camper’s overall footprint. An industry-first under-bed storage compartment further improves organization, making it easier to keep gear stowed and accessible.
Heating, Power, & Upgrades
The Flagship HT includes a Truma Combi air and hot water heater as standard, running on propane. For those driving diesel-powered trucks, Supertramp offers a diesel-powered version of the same system as an upgrade, making it easy to streamline fuel use for those already carrying diesel on board.
Supertramp equips the Flagship HT with a 200Ah Victron lithium battery — enough to keep the lights on and power basic electronics overnight. For extended off-grid travel, buyers can upgrade to 800 Ah of heated lithium batteries, a must-have if opting for the available 12V air conditioning system.
With this setup, owners can run the air conditioning throughout a hot night without needing a generator, making summer camping far more comfortable.
The electrical system supports 330 W of roof-mounted solar panels. For those needing more power, Supertramp offers an external solar array input. This allows for additional portable solar panels to be connected, expanding charging capability beyond what’s possible with the limited roof space.
Buyers can also choose between 30A or 50A DC-DC charging, ensuring reliable power whether driving or parked in a remote location.
The camper’s water system includes a 24-gallon fresh water tank and a 5-gallon under-sink grey water tank, providing enough storage for multiday trips. Two 11-pound propane tanks fuel the standard heating and hot water system, giving owners plenty of runtime before needing a refill.
More Customization & Considerations
Supertramp offers several optional upgrades to further enhance the Flagship HT. Customers can add an enclosed ski locker for winter gear storage, a Starlink Mini for off-grid internet, and an induction cooktop for those looking to move away from propane.
Other available options include AC power inverters and an interior shower with an additional 5 gallons of water storage. An optional Guzzle H2O filtration system adds an extra layer of security for off-grid adventurers.
While these features improve the camper’s versatility, they also add weight. Given that truck campers depend on a vehicle’s payload capacity, buyers should ensure their truck can handle additional upgrades before finalizing their build.
Supertramp Hardside: Interior, Exterior Styling
Supertramp designed the Flagship HT for off-road travel but didn’t neglect the aesthetics. The camper has a high-gloss automotive paint finish and comes standard in a “High Gloss White” color, while Rhino Liner protects the base and down-facing edges from rock chips and road debris.
Customers can also choose from three optional colors: Battleship Grey, Forest Green, and Desert Tan. Plus, Supertramp offers custom colors to paint-match your vehicle or vinyl wrap upgrades for those who want a personalized look that complements their truck.
Inside, the Flagship HT is available in two design themes. The Glacial Valley package has cool blue tones, while the Desert Mesa package incorporates earthy oranges and browns.
Multiple cushion color options allow for further customization, giving owners more control over the camper’s interior aesthetic.
Supertramp Flagship HT: Who It’s For
I’ve been impressed with the quality of Supertramp Campers from the start. When it launched the Flagship LT, it was the first time I seriously considered a pop-up truck camper.
Now, with the HT, it’s done the same thing for hard-sided models. The brand’s approach to design and construction stands out in a segment that’s often dominated by mass-produced RV-style campers built with cheap materials that seem unlikely to hold up to real off-road use.
The biggest advantage of a slide-in camper is that it allows you to keep your truck practical for daily driving. When it’s time for an adventure, you can load up the camper with minimal effort and hit the road. That flexibility is something I appreciate, especially compared to setups where the truck and camper are permanently attached.
The challenge with most truck campers has always been finding the right balance between weight, durability, and aesthetics. Many lightweight options aren’t built for serious off-road travel, while the heavy-duty ones are often too bulky, overweight, or just plain ugly.
The Flagship HT strikes an impressive balance, offering premium materials, smart design, and true off-road capability in a package that doesn’t sacrifice looks.
