Truck Camper Magazine dives deep into a 2025 Supertramp Flagship LT and discovers layers of design detail we hadn’t seen before. The quality is remarkable, but is this the right camper for you?
On the last day of our Supertramp factory visit, a Flagship LT was being prepared for delivery the following morning. The completed camper was positioned at the bay door waiting for its new owner to arrive.
With the glistening fiberglass camper sitting there, we took the opportunity to explore the entire unit. We had seen Supertramp campers at Overland Expo, but this was our first opportunity to really go through one stem to stern.
Loaded on a wheeled cart, the Supertramp Flagship LT was customer-selected in white with grey Dolomite decals.
All Supertramp campers start off white but are also available in Battleship Grey, Sand Dune Tan, or Forest Green 3M wraps. The 3M wraps are paid options and won’t reflect the sun as well as the base white. It’s a personal preference, but I think the white and grey tones look particularly clean and sharp on this camper.
Note the metal basket, paperwork, and boxes under the cabover. The basket contains the completed order form and quality control checklists that followed the camper throughout the two Supertramp factory facilities. The boxes contain the Rieco-Titan jacks.
“But, Gordon,” you say, thrusting up a hand, “the camper already has Rieco-Titan jacks. Look at your pictures.”
Yes, that’s true, but the Rieco-Titan electric jacks shown on the camper are factory jacks. Those jacks will be removed when the camper is loaded onto the camper. Why? Because most Supertramp Flagship LT customers do not travel with the jacks installed.
In the Overland world, corner jacks are too easy to catch on a rock face, tree limb, or sharp departure angle. Instead, the customer will take the standard Rieco-Titan convertible jacks (upgradable to electric) home inside their truck or new camper, and use them when they need to unload their camper.
The 42-inch Arctic Tern window pictured above is a very popular option. In fact, the Supertramp owners we’ve talked to said this option should practically be standard for all the light and functionality it brings to the camper. Of course, Supertramp is keen on keeping their entry price as low as possible, and big windows are expensive.
Along the lower solid wall of the passenger’s side is where we found the Truma exhaust port, shore power port, and the 24 gallon fresh water fill.
The rear of the camper has a lot more going on. First, note the large MOLLE pattern panel on the driver’s side. This can be used to mount Rotopax, traction boards, shovels, and other recovery tools.
Next, bring your attention to the black and aluminum actuators. Supertramp uses an electric lift system that raises and lowers the roof at the push of a button and doesn’t require latches.
See the Torklift turnbuckle hanging on the lower left? The lower actuator bracket doubles as the tie-down point for a Torklift turnbuckle system. That’s not just good design, it’s where form meets function meets a decidedly modern aesthetic. Brilliant!
The door itself—like the entire camper shell and interior—is made from vacuum-infused fiberglass and has a built-in thermal pane window and shade. When we closed this door it made a very satisfying, and solid sound. This is one well-built camper.
Supertramp utilizes an RVLock V4.0 keyless lock system. This all-metal lock comes with two FOBs, has a backlit keypad, and features a lifetime warranty. As long as you can remember your security code, you can leave your keys in the camper. Just don’t use 867-5309.
Supertramp has numerous Easter Egg details for owners to discover. For example, note the Supertramp “ST” logo in the lower part of the grab handle. That’s some serious design love right there.
Above the door, the Rigid brand LED lighting is standard and the backup camera is optional. If you’re towing or often have to back up without a spotter, a backup camera is essential.
On the rear passenger’s side is the propane compartment holding two 11 pound propane tanks. Here we find more delicious Easter Egg design details like the Supertramp logo strap and the in-house designed slide-out tray.
Eleven pound propane tanks are unusual in the broader RV marketplace, but are relatively common within the Overland community and widely available. By utilizing two 11 pound tanks, they are getting 22 pounds of capacity in a narrower space than a more typical 20 pound vertical tank would require.
As the trend toward all-electric camper designs progresses, I can see more camper companies switching to this two 11 pound tank approach to (a) save interior space and (b) run the furnace and water heater (or combination unit). These appliances are the most demanding on electric power and thus the most impractical to make all-electric.
If and when Supertramp wants to offer an all-electric camper, this same compartment might fit a Honda EU2000i portable generator. That would be an interesting test.
On the rear driver’s side is the only exterior storage compartment. It’s small, but perfect for items like water hoses and electrical cords. This might have been a deficiency of the design if not for the large storage area behind door number one.
Just inside the camper entry door is a huge slide-out tray. In an ideal world you would be able to access this slide-out tray without keeping the door open to bugs, but wow is that a huge amount of storage space.
Since this storage is inside the camper and is 100 percent protected, you could use it for anything and everything—extra clothing, dry foods, fishing gear, a metal detector and shovel, etc.
From the entry door, the Supertramp Flagship LT presents a modern and open space. When you unzip, fold down, and secure the window insulation, it’s another world…
Supertramp completely rethought the possibilities of pop-up soft wall windows and went big and gorgeous. Where traditional pop-up windows are generally smaller and rectangular, the front window of the Flagship LT wraps around the front corners and angles down. The side windows are huge and also angle down. The rear window follows suit.
Just having soft wall windows 360 degrees around the camper is significant. Having them so large and stylized is next level. Those with an eye for design will appreciate the lines and how the angles meet.
The most feature-dense area of the camper is the fiberglass kitchen module. Here we find the flush mount two-burner propane cooktop, sink and faucet, 12-volt compressor refrigerator, slide-out drawer, Truma Combi furnace and water heater, electrical system, fuse panel, battery bank, lower cabinetry storage, and control panels. It’s packed.
Again, the well-thought-out design is what stands out. The result is the most elusive of design achievements—simplicity. One can look at everything in this kitchen area and immediately understand and access each component and control. It’s not easy to make things this intuitive.
Yes, it will take some time and possibly a video to fully understand the Truma Combi, but you can easily find it, access it, and control it within seconds. Overall the kitchen presentation seems like kids play because the Supertramp team designed it so well.
The two-burner flush mount propane cooktop is plenty for a camper this size. In our much larger hard side camper, we have three burners and use only one burner 99 percent of the time.
My only thought here is whether an induction cooktop would make more sense. The challenge is that an induction uses between 1,000 and 1,800 watts depending on the heat level. With enough solar power, a large enough lithium battery system, and a 2,000 watt inverter (all on trend in the truck camper marketplace), an induction option would be worth consideration.
Next door, the sink is appropriately sized for washing dishes, washing hands, and brushing teeth. Best of all, there’s still a ton of counter space available for food prep. If you enjoy cooking on the road, this camper is ready for gourmet adventures.
I love stuff like this. Your first take might be, “It’s just a drawer. Big deal.” Well, it’s not just a drawer. It’s an aluminum drawer. That means it’s strong, light, and maximizes the amount of storage it offers (no thick wood sides).
And yes, it’s a drawer! Far too many truck camper designs don’t have drawers. And even better, it’s a kitchen drawer under the counter perfectly sized for silverware and utensils.
Who doesn’t have a kitchen drawer in their house with silverware and utensils? It’s one of those obligatory storage items everyone takes for granted in their homes, but is sometimes missing in a truck camper.
The Supertramp Flagship LT comes standard with a 65L Isotherm 12 volt refrigerator. For those not in the liter-verse (like me) that’s 2.3 cubic feet. This is a fairly standard size of refrigerator for pop-up campers that have built-in refrigerators. Although we have not independently verified it, Supertramp reports the standard 330-watts of solar keeps this refrigerator powered.
For weekend adventures, 2.3 cubic feet is probably more than enough. For those who need more capacity for longer adventures, an additional 12-volt portable cooler-style refrigerator would make sense. We’ve seen plenty of folks with pop-up and hard side campers that have a portable cooler-style refrigerator in their camper or truck.
I know this is a small detail, but note how the fiberglass kitchen module has a countersunk space for the LP detector. This kind of effort is simply unheard of throughout most of the RV industry. Why not just install it on the flat surface of the kitchen module?
The reason is pure passion. Time and time again, Supertramp takes the time and effort to make their campers as elegant as possible. Is this the most impressive LP detector installation we’ve ever seen? You’re darn tootin’ it is.
And while we’re darn tootin’, note that the refrigerator is also countersunk into the fiberglass kitchen, as are all the other kitchen components. Everything is essentially flush mount for a more attractive presentation, and a few precious millimeters of interior space. To paraphrase Monty Python, every millimeter is sacred.
To the right of the refrigerator is an aluminum door with a decent amount of storage for cups, dishes, and dry food. The control and hoses at the top are for the inside shower enclosed inside the rear dinette seat directly across from it.
Beyond the space shown above and the pull-out drawer in the kitchen module, there’s no upper cabinetry storage in the kitchen, or anywhere else in the throughout the camper. On balance, there’s a ton of storage located under the dinette seats and under the cabover bed.
While we’re here, I want to bring your attention to the switches to the immediate left (in the photo) of the vacuum-infused fiberglass entry door. These switches are conveniently located when you open the door.
From top to bottom, these switches control the raising and lowering of the electric roof lift, the water pump, interior light, and exterior light. Having the interior light switch immediately inside the door is fantastic. We’ve tested far too many campers that require you to enter the camper in the dark before turning a light on. No such issue here.
To the left of the refrigerator is where the Truma Combi furnace and water heater, electrical system, fuse panel, and battery bank reside.
The Truma Combi has become a new standard in the truck camper industry. It’s not the right solution for every truck camper make and model, but it’s increasingly popular for its space savings and efficiency.
You may have noticed the control panels and on-off button located at the base of the Truma Combi. These are the Victron Energy battery monitor, Blue Sea Systems tank meter, and a button to turn on the tank sensor. Note how the aluminum bracket is curved with the three round items it contains. This team can’t help themselves from making everything look awesome.
Under the Truma Combi is the Supertramp in-house manufactured electrical system subassembly. Supertramp builds their own electrical systems and tests them before they get installed into campers. This approach not only ensures the quality of the electrical system, but speeds up camper production.
The Supertramp electrical system utilizes a Blue Sea Systems fuse block, Blue Sea Systems Bussman resettable circuit breakers for solar (150A) and DC-to-DC (100A), a Victron DC-to-DC converter, MPPT solar controller, and SmartShunt Bluetooth battery monitor.
We selected a Blue Sea Systems fuse block for our own camper, and have heard nothing but positive feedback on Victron components for their performance and reliability. We also appreciate that the 12-volt fuses are accurately labeled for quick troubleshooting.
Under the electrical system subassembly is the standard Battleborn 100Ah lithium battery. To the right is a second optional Battleborn 100Ah lithium battery. Supertramp can install up to 400Ah of lithium batteries. If you’re even thinking of using air conditioning off-grid, go for 400Ah.
Between the front wall and the kitchen module is where you find the Truma control panel, MaxxAir remote control, and a range of outlets; two 110-volt, one USB-C, two USB-A outlets, and two 12-volt outlets. There’s also a heat duct pointed to the cabover bedroom.
I can see owners using the kitchen countertop and outlets as a charging station. Ideally there would also be 110-volt and USB outlets in the dinette and cabover for charging devices and powering a CPAP machine. Of course the camper is not that large, so running cords to either the dinette or cabover would not be a challenge.
Directly across from the kitchen is a wide open seating area. What you’re not seeing here is the optional Lagun table system. The customer who ordered this particular camper didn’t order that option.
This is a good time to remind everyone that Supertramp only sells direct from their Golden, Colorado factory, and that each camper is custom ordered from a generous, but fixed option list. Supertramp is happy to build the exact camper you want, as long as what you want is on their option list.
Earlier I talked about how the 42-inch side window is considered a mandatory option by many Supertramp customers. Here you can see why. Even with the windows zipped up, the window is letting in lots of light. And I’ve been told by Supertramp customers that this window makes sleeping in the camper with the roof down comfortable.
The acrylic thermal pane window opens and features a built-in bug screen and black-out shade. We have camped many times with this style of window and they take a bit of practice to use. Once you have the knack, they’re a snap and offer excellent insulation quality. The warmest campers we’ve ever used had acrylic thermal pane windows.
The black-out shade is also highly effective. With the black-out shade up, very little, if any, light is visible from this window. If all of the soft wall windows are zipped shut, and the black-out shade is up on both this window and the rear door window, the unit would be essentially dark from the outside. If you like to stealth camp, the ability to have a dark camper from the outside can be important.
Remember when I said there was a lot of interior storage in this camper? It starts under the rear dinette cushion. Lift up the black aluminum plate and there’s a space that can be used as storage, and/or the interior shower pan, and/or where an optional Thetford 365 portable cassette toilet can be stowed. For pictures of the shower and toilet in this area, check out our Supertramp Flagship LT introduction article.
Under the middle dinette seat is more storage and a fire extinguisher. Note that the inside of the dinette is finished.
The forwardmost dinette seat also lifts up, but this time with a strut assist. This storage area is also finished, and—like that box of Fruit Loops or Lucky Charms that you had when you were a kid—has a Free Prize Inside!
Under a false floor are the 24 gallon water tank and the water pump! Okay, so it’s not a secret decoder ring, but we’re thrilled to have direct access to the water tank and especially appreciative to have easy access to the water pump. Oh, and there are those Supertramp branded straps again. Supertramp belts and suspenders anyone? I’d take a belt.
Water pumps are notorious for needing to be replaced. Having the pump easy to access is truly excellent. You can also see how the wiring and plumbing are neatly dressed and tied.
There’s not much to talk about in the cabover; no cabinetry, no outlets, nada. What is there—the cushion—is incredibly well made.
We met the cushion team at Supertramp and they are dialed in and dedicated to making the best cushions. Not the best cushions for a pop-up camper, but the best cushions period. From the stitching to how tight and perfectly shaped the cushions are, these cushions are first class. And they’re quite comfy too.
Like many pop-up campers, the cabover in the Supertramp Flagship LT lifts up to present a ton of storage. The bed has two Supertramp straps to grab and lift and is then is held in place with two struts. The molded vacuum-infused fiberglass base is divided into four equal storage areas that would easily swallow the stored contents of our 11-foot hard side cabover with all its built-in cabinetry.
This is where most folks will probably store their clothing. Of course, there are no laws currently on the books against storing dry foods and gear in this location.
The soft wall windows unzip left to right with a heavy-duty zipper that oozes with quality. The thickness of the insulated soft wall is also impressive. Note how the unzipped portion has six rectangular strips of Velcro.
Put the two Velcro rows together and you have a neatly folded window. You can leave the window like this if you’d like, or take it one step further.
Each window has a set of ties that allow you to roll up the window and make an even neater and tighter roll. The quality of the materials and design make unzipping, Velcroing, rolling, and tying the windows quite easy and satisfying. How easy and satisfying? Shown above is my first time engaging the Supertramp soft wall windows and I think I did a most excellent job. That’s how.
Here’s the mic drop moment. After all the other details we discovered, the Supertramp logo on the color-coordinated rubber grippy window zippers is over the top. Peace sign raised. Hand on the heart. Exit stage left. Supertramp has left the building.
I’ve been accused of lying down on the job many times, and I’ll freely admit to it. Sometimes it’s the only way to get a photo. Other times I’m just tired. Thankfully, nobody was looking when I hit the Flagship floor and snapped this image. I’ll just close my eyes for a minute…
Note the two fans fore and aft. Note the four ceiling lights. Note the one-piece vacuum-infused fiberglass roof. Note the interior actuators. What you don’t see is the optional air conditioner.
Is the Supertramp Flagship LT the Right Camper For You?
Having now spent days at the Supertramp factory and studied Flagship LT end-to-end, there’s no denying the design and build quality. It’s simply off the charts in every detail. And there’s a lot of amazing detail.
But, Supertramp only builds one pop-up truck camper model. If want a different floor plan, upper cabinetry, the latest appliance or battery system, a flatbed version, or anything else not reflected in the Supertramp Flagship LT and its option menu, you’ll need to look elsewhere.
Beyond that, the Supertramp Flagship LT is one stunning pop-up camper. If what they’ve designed suits your pop-up camper needs, the Flagship LT should be on your very short list.
Factory Tour
So much of what you’ve just read is the result of the process, materials, and culture of Supertramp. And that, my fellow truck campers, is infused into every facet of our Supertramp factory tour article from this past June. If you’re interested in Supertramp and haven’t already read our factory tour, I recommend taking a look at that article.
