The Stronghold- Hard Sided Electric Roof Top Cabin
The Stronghold by Sparks Overland
Carbon Fiber All-Season Rooftop Cabin with Electric Lift & Climate Control Compatibility. Made to order. Please allow 3 months for production.
The Stronghold isn’t a tent. It’s a rooftop cabin—engineered for serious overlanders, long-range explorers, and families who refuse to compromise when the weather turns hostile. Designed for adventure vans and mid-size trucks, the Stronghold delivers true four-season protection, refined comfort, and uncompromising strength in one purpose-built system.
This is shelter you trust when conditions don’t care.
Carbon Fiber, Done Right
The Stronghold’s carbon-fiber outer shell dramatically reduces weight while increasing stiffness and impact resistance. That means better handling, higher payload efficiency, and a structure that thrives under vibration, wind, and miles of abuse.
We didn’t choose carbon fiber to look impressive.
We chose it because it’s stronger, lighter, and smarter for real travel.
Purpose-Built Features
- Electric Lift System
Deploy your cabin at the push of a button. The remote-controlled electric lift raises the shell smoothly and quietly in seconds—no cranking, no climbing, no struggle. Included is an emergency, manual back up system.
Bottom Entry Design
A strategic bottom hatch keeps all four walls sealed and fully insulated. The result: superior warmth retention, precise airflow control, and exceptional weather protection—while keeping dirt, snow, and debris outside where they belong.
Spacious, Livable Interior
With 82” x 55” of sleeping space and 39” of interior height, the Stronghold comfortably sleeps two adults and one child, with enough headroom to sit up, change, and move freely. Interior space to fit a full size mattress.
- All soft touch interior with "R" value of 9
- Built in LED lighting
- Max Air ventilation fan
- Optional built-in mattress
- Slide open windows with built-in screens
True Four-Season Insulation
A rigid FRP (fiber-reinforced plastic) shell paired with a PET insulated core delivers thermal efficiency, sound dampening, and structural integrity. From winter storms to desert heat, the Stronghold is built to perform year-round.
Off-Grid Power Ready
Optional integrated lithium power supports lights, fans, heaters, AC, and accessories—without draining your vehicle battery. Optional 400W solar capability keeps you self-sufficient far from civilization.
Hard-Shell Confidence
Engineered to withstand max 40MPH winds, heavy snow loads, and relentless road miles. This is a cabin built for expeditions, not just weekend escapes.
Secure & Refined
Push-button electronic locking offers quick, reliable security—no keys, no hassle. Simple, modern, and built to last.
Because shelter should be your strongest piece of gear.
