A Ford F-450 or F-550 can carry a full-size camper, and OEV builds a few ways to do it. The High Country flatbed pop-up is the one that puts the full floor plan and off-grid power of a big rig into a removable pop-up, one that drops to 64 inches for travel and lifts off when you don't need it.
The High Country flatbed pop-up is the largest pop-up in OEV's removable flatbed line. The body runs 193 inches long and 81.25 inches wide, drops to 64 inches closed for travel, and opens to an 81-inch exterior height. It's built for owners who already have the truck and for anyone building one from the chassis up, a camper sized to match without giving up the pop-up.

Here's a full walkthrough of the High Country flatbed pop-up:
The Full-Size Floor Plan
The base sits 8 feet on the flatbed tray, the same footprint as the Hudson Bay 8'. What's different is a rear kick-out that extends the interior to 9 feet 6 inches wall-to-wall, front to back. That extra foot and a half is what opens up the layout inside.
Here's what the 9-foot-6 interior makes room for:
- A U-shaped dinette for eating, working, and hanging out
- A queen bed that sleeps 4 or more
- A wet bath standard, the toilet and shower together in one sealed space
That's a full-size camper's floor plan in a pop-up that still drops down low for travel.

Big-Rig Power and Water
The High Country is sized for longer stretches off-grid. It carries 440 watts of roof solar on two 220-watt panels, with room to expand, feeding a 3,000-watt Victron inverter with a Cerbo GX to monitor and manage the system. A 130-liter Isotherm drawer-style fridge and freezer handles the food. Fresh water is 38 gallons with a 12-volt pump and a sight gauge, and unlike the lighter-duty pop-ups, the High Country holds 15 gallons of gray water right in the cabin. Heat and hot water come from a Truma Eco Combi.

Still a Pop-Up
Here's what sets it apart: all of that drops down to 64 inches for travel and storage. Construction is composite panels on OEV's aluminum exoskeleton, the same build that runs through the whole line, so there's no wood to rot and no particle board to shake loose. It's lightweight for its size, expedition ready, and built to stay under your GVWR. For the flatbed mount, OEV recommends the HD or HDX from Aluma Tray, its sister company under the Lite Industries umbrella.

Which Truck It Fits
The High Country flatbed pop-up is built for Ford F-450/550 and RAM 4500/5500 trucks with a 60-inch cab-to-axle. If you're already running a super-duty or cab-chassis truck and want a four-season camper sized to match, this is the one in the OEV line built for it.
High Country or Hudson Bay?
Both are removable four-season pop-ups on the same OEV DNA. The difference is the truck under them and the room inside.
| Spec | High Country Pop-Up | Hudson Bay Pop-Up |
|---|---|---|
| Interior (wall-to-wall) | 9 ft 6 in | 8 ft (both lengths) |
| Truck fit | F-450/550, RAM 4500/5500 | 3/4 to one-ton |
| Dinette | U-shaped | Standard |
| Solar | 440W (expandable) | 220W (expandable) |
| Gray water | 15 gal in cabin | Drains to container |
| Price (USD) | From $125,205 | From $88,392 |
Running a 3/4-ton or one-ton instead? The lighter Hudson Bay flatbed pop-up gives you a full 8-foot interior and the same wet bath in a smaller package.
