Supertramp Flagship HT – Hard-sided Slide-in 6.5' Pickup Camper

The third week of February, 2025, I had the opportunity to travel to Supertramp Campers (STC) in Golden, Colorado to spend four days/three nights winter camping in a new camper model.
As of February 24, 2025, STC has released the Flagship HT (Hard Top). It is a hard-sided, slide-in camper designed for a 6.5' pickup bed or tray and is the third production camper model by the company. It is based on the well-sorted Flagship LT (Lift Top) pop-up camper that the company has been building for four years.

Base price is $65,975.

Dimensions
The interior standing headroom is 6'6”. This sits in about the middle of the typical hard sided camper standing-headroom range. For comparison, the Flagship LT pop-top camper, has 6'9” of standing headroom. Three inches less standing headroom is a reasonable compromise between enough headroom (both standing and in the cabover) and keeping a slightly lower overall exterior height for overhead clearance on trails and around town. This also keep the center of gravity lower and helps aerodynamics.

The light weight of the HT also contributes to drivability. The dry weight of the HT is about 1,400lbs with standard equipment compared to about 1,350lbs of the soft-sided LT (both weights can increase significantly as options are added).
Weight was removed with the subtraction of the LT roof actuators and the embedded steel roof actuator plates, soft-top material, wiring, etc. Weight was gained back from the hard walls, six windows, aluminum interior cabinets and interior molle panels. Net gain was only 50lbs. Keep in mind that some accessories will impact center of gravity differently between the HT and LT due to location. Example being rooftop Dometic DC air conditioner. But, I suspect the extra 75lb, even on the rooftop, would mainly be noticed if driving with and without it back to back. These are overall very light weight campers compared to some of the much larger and heavier (10'+ and 4,000lb+) hard wall campers that require 1 ton dually pickups. These will be perfect on any 3/4 ton pickup.



HT-specific Features

I'll touch on Flagship HT features, that differ from the Flagship LT, at a very high level for now. In later posts, I'll cover these features in more detail as well as share details on all the standard and optional equipment that is shared with the LT.

- Windows
The HT's hard top has six Arctic Tern “Flat” windows: one front, one rear, and two on each side. I've started referring to these windows as the “Black Edition” because the window frames are black rather than white, the inside of the shade is black rather than white, and they have a tinted acrylic two-pane window rather than clear. Another slick design feature is the exterior of the acrylic window pane is flat rather than curved outward, hence Arctic Tern referring to them as Arctic Tern “Flat” windows.

- Cabinets
There are two aluminum cabinets mounted up high. The triangular corner cabinet, above the sink, has two individual compartments. The larger rectangular cabinet, starts immediately above the control panel and goes up to the ceiling. It also has two doors, but the compartments are large enough that they are split with shelves inside. There are small openings on the cabover side allowing access to the upper cabinet and access to a small cubby which is handy for quick access. The cabinet blocks the usual location for one of the three cabin heat outlets so that particular heat duct is extend through a portion of the cabinet and routed up to vent into the cabover.
Dimensions:
Closet cabinet: 36.75" x 20.75"
Kitchen cabinet: 20" x 21.5"

- Interior Molle Panels
There are two internal molle panels on the driver's side interior. The rear corner panel is made up of a two-plane molle panel. The other molle panel is situation between the two driver's side hard-top windows.
Front: 22.24" x 24"
Rear: 24" x 24.5"
Weigh limit estimate at 50lb each (to be confirmed)











My future posts will cover, in detail, the Flagship HT standard and optional equipment, my driving and camping impressions from the trip, etc. Meanwhile, here are some more photos from my trip.

Supertramp Campers
For those unfamiliar with STC, founders Keith and Kelsey Panich have been researching and working on camper designs since 2017. The company shared it's first camper prototype in 2020. Known as the Flagship, it was a unique three-quarter hard-sided camper, meaning the main cabin of the pop-up was hard sided and the cabover was soft-sided. By the following year (2021), the design had transitioned to a full soft-sided pop-top designated the Flagship LT (Lift Top). Like the prototype Flagship, the Flagship LT is a slide-in camper designed for a 6.5' pickup bed or equivalent-sized pickup tray. As of February 2025, they have built and sold nearly 160 Flagship LT. https://www.supertrampcampers.com/products/flagship-lt

In 2024, STC partnered with Liquid Spring LLC and Elevation Off Grid (EOG) to introduce the larger, turn-key model named the Megatron and the first order builds are underway. That model uses an Elevation Off Grid (EOG) Black Edition Ford F550 chassis with Liquid Spring suspension and 41” tires. https://www.supertrampcampers.com/products/megatron

Model Introductions
STC continues to expand their line-up and there will be more models in the future, but they are methodical in their new-model introductions to ensure well thought out designs. In personal conversation with Keith and Kelsey, they shared that they are not chasing the most in-demand or lucrative camper form factors. They choose to introduce models based on their own desire and what they personally want to use and it shows in their final product.

Interestingly, based on market research including personal interviews with interested customers, STC discovered that the pop-up camper and hard-sided campers are not cross-shopped as often and one might expect. The hard-sided camper shopper is more likely cross-shopping other hard-sided campers (removable or permanently mounted) and camper vans.

While no new models will be released in 2026, future models are always being considered. Be that an 8' version of the pop-top or hard-sided Flagship line, a smaller version of the permanently mounted Megatron, or even tow-behind campers, the team is always thinking about their next passion-project.

Flagship LT Design
The HT was a logical choice for the next model. The tub of the Flagship HT camper is the exact same vacuum infused composite shell and layout as the Flagship LT. The roof itself is the same as the LT (dimensions, wiring, lights, fans/vents, etc) except a new mold was created to add the hard walls to the existing roof design. The layout, cabinetry, components, etc., from bed-level/counter-top level downward, matches the LT camper, meaning it is a mature product at birth. Through a proprietary process, the hard top is bonded to the tub. Trim is molded into the hard top, is masked and coated a contrasting color, and expresses where the hard top bonds to the tub.

seems they’re using the same forms for the body as the LT, then slapping a lid on it. Economical i guess, but i don’t care for that seam.

disappointed they didn’t go hard side flatbed, which they originally planned back in 2021. Had a pretty trick collapsing roof similar to rossmonster.

Yes, same tub as the LT with new form for the hard top and then bonding, as outlined above. The seam is painted afterwards. Likely one could get it without the black contrasting coating if one didn't want the black line. There will still be a seam though.

The prototype of 2020 was the 3/4 hard top I mention above. It was a slide-in; not a flatbed. 3/4 of the pop-up was hard-sided and the cabover was soft-sided pop up.

 

[calameda]

It was a flatbed. Kelsey sent me their CAD drawings. Ask her about it.

Ah, I gotcha. I misinterpreted your comment and thought it was a prototype, like the 3/4 hard top, rather than drawings.
Would love to see them if you still have them. I'll DM you tonight. I love that kind of stuff.

I completely agree. I would never buy it as it looks above.

Now if the seam material could be the same color as the camper, then possibly. But I definitely don't like that is introduces a very long seam that could leak.

If they know what they are doing, leaking shouldn't be a problem. Boat builders have all kinds of seams to deal with.

So if I’m reading this correctly the standard unit does not come with a Truma combi heater? I believe the pop-top has it standard. While it’s a hard side and has better insulation values my assumption is that everyone will want a heater to extend it into a 4 season camper. Otherwise as it is it’s a 3 season.

The Truma is standard (is listed above) and can be upgraded to the Truma Combi Eco Plus.

Not a big fan of the outside design (I would have to see it in person for a better view), but I really like what they did on the interior with the windows. So much light from the upper windows - great job, STC team!

This is not a camper I would purchase, but that is due to my use case being very different. I also have not seen this in person - so, my feedback may be different once I have seen one. But with that out of the way, here are my initials thoughts.

- I love the windows and the light they provide
- Love the additional storage and that it is easier to access
- This thing is ready for some really cold weather (yay). I would definitely feel confident taking this to the arctic circle in February.
- Great job with the Molle panel placement

Here are my initial thoughts about making it even "better" (better in the eye of the beholder ):

1) I would definitely like to see an HT with the driver-side lower window.
2) Make the cabinets near the bed a tiny little bit deeper. I'd think 1-2 inch would go a long way.
3) Embedd power outlets (at least USB-C) into the cabinets near the bed so that it is easier to charge phones overnight
4) I can already see myself bumping my head at the over-the-sink corner cabinet when washing my face. Personally, I would extend the cabinet further down to move the edge further down or make it a shelf below so that the edge is further down
5) Use the cabinets to add some mood light options
6) Get rid of the rear window and rather put a larger door in.
7) Fill the space under the cabinets with an open shelf that can be detached if needed. That way a smaller person could still sleep on that bench.

Ah gotcha. I missed that part.

Yeah, they said it would actually be easier to not add the color. The roof section is painted (be that the standard white or one of the optional paint colors). Once complete, then they went back and masked off the trim and coated it black. I don't say paint because it's more like the Raptor/Rhino type liner than plain black paint.

Here are a couple quick and dirty photoshopped image without the black belt (and the original with black belt). One without the trim altogether and one with it camper colored. I never claimed to be a graphic designer and only spent 1 minute on each, but it gives one the idea.
