When most people think of tiny homes on wheels, they picture converted vans or school buses. But a growing community of adventurers is turning to something far more rugged: retired ambulances and firetrucks. These heavy-duty emergency vehicles were built to survive the worst conditions imaginable, making them surprisingly ideal platforms for full-time living. From a hand-built walnut-clad ambulance that’s visited 48 US states to a two-story German firetruck carrying a family of six across Europe, these seven builds prove that the best adventure rigs sometimes come with sirens still attached. Here are seven of the most creative emergency vehicle conversions we’ve found.
1. The Lost Box — A Walnut-Clad Off-Road Ambulance Motorhome

Tom Roszko spent years transforming a 2009 Chevrolet Kodiak C4500 ambulance into one of the most refined emergency vehicle conversions on the road. With roughly 200 square feet of interior space and a 14,000 lb GVWR, this 4×4 ambulance was already built for punishment — Tom just made it beautiful.
- Hand-built walnut cabinetry throughout the entire interior gives it a warmth most RVs can only dream of
- Moroccan tile backsplash in the kitchen adds artisan character to the galley
- Full off-grid systems including diesel heater, composting toilet, and solar power
- 48 US states plus Central America — this rig has been thoroughly road-tested
The total build cost landed around $80K ($44K for the ambulance plus roughly $35-40K in conversion costs), which is remarkable considering the craftsmanship involved. The Kodiak C4500 platform gives him go-anywhere capability that most converted vans simply can’t match.

2. The Glambo — A Solo Female Build That Lives Up to Its Name

Rachel turned a 2006 Chevrolet Kodiak C4500 ambulance into what she calls “The Glambo” — short for Glamorous Ambulance — and she did it in just three months on a remarkably tight budget of around $25K total ($14K purchase plus $8-10K in build costs).
- 14′ x 8′ living space with over 6 feet of ceiling height — rare in vehicle conversions
- 1,065W solar array with 400Ah lithium batteries and a 3,000W inverter for serious off-grid capability
- Vaulted ceiling loft with skylight windows that flood the space with natural light
- Reclaimed barnwood accents that add rustic warmth to the interior
What makes The Glambo stand out is the combination of speed, budget, and style. Rachel proved that a solo builder can transform an ambulance into a genuinely beautiful living space without spending years or a fortune doing it.

3. Team Wiff — The $3K Auction Ambulance

Will and Tiff — known online as “Team Wiff” — scored a 2008 GMC C4500 Topkick ambulance at auction for just $3,000. That kind of entry price makes ambulance conversions accessible in ways that traditional RVs and even van builds often aren’t.
- $3K purchase price at auction — one of the most affordable starting points we’ve seen
- 6’4″ interior ceiling height means even tall occupants can stand comfortably
- 2,000W solar system paired with 400Ah lithium batteries for full off-grid living
- Couple’s build designed for full-time life on the road together
The GMC Topkick platform shares DNA with the Kodiak, offering the same heavy-duty reliability that makes these ambulances so appealing for conversion. At $3K for the base vehicle, the Topkick represents one of the best value propositions in the ambulance conversion world.

4. Bombero Travel — A Two-Story German Firetruck Crossing Continents

Anna and Sebastian Schlüter, a German couple, took on one of the most ambitious builds on this list: converting a 1987 Mercedes-Benz 1113 firetruck into a full two-story home on wheels with a pop-top roof. The name “Bombero” means firefighter in Spanish — a nod to the truck’s origins.
- Full two-story layout with a pop-top that creates a second level — dramatically expanding livable space
- ~$14,700 total cost (purchased for roughly €3,000) making it an incredibly budget-friendly build
- 19+ countries visited and still going — this truck was built for serious overlanding
- Weight reduction engineering — they decreased the 11-ton vehicle to 7.5 tons during conversion, which is remarkable
The year-long conversion process required serious engineering, particularly the weight reduction work and the pop-top mechanism. But the result is a home that offers space and functionality most overlanding rigs can’t touch, at a fraction of the cost.

5. Dare2Go — Two Decades of Overlanding in a German Firetruck

Yasha Langford and Juergen Klein are an Australian-German couple with over 20 years of overlanding experience. Their current rig, affectionately named “Berta,” is a 1981 Mercedes-Benz 1019 firetruck originally from the Helmstedt fire department in Germany.
- Four-wheel-drive capability from the factory — essential for the remote terrain they seek out
- 175L fresh water tank plus dual fuel tanks totaling 400L for extended range in remote areas
- 20+ years of overlanding expertise built into every design decision
- Purpose-built for remote travel — this isn’t a weekend camper, it’s a serious expedition vehicle
What sets Dare2Go apart is the depth of experience behind the build. After two decades of living on the road, Yasha and Juergen know exactly what works and what doesn’t. Every system and layout choice in Berta reflects hard-won knowledge from years of real-world travel.

6. Roaming Embers — A Fire Truck That Still Uses Its Water Pump

This one might be the most creatively resourceful build on the list. The couple behind Roaming Embers converted a 1995 E-One pump truck — and they kept the original water pump operational for use as an outdoor shower. That’s the kind of thinking that makes emergency vehicle conversions so interesting.
- $25K all-in ($8,600 at auction for the truck) — impressive for what you get
- 26kWh DIY LiFePO4 battery bank built from 1,680 recycled 18650 cells harvested from old scooter batteries
- 2,400W solar + 6,000W inverter for serious off-grid electrical capacity
- Hydraulic tilt cab for easy engine access — a feature unique to fire trucks
- 8.3 Cummins engine + Allison 3060 transmission — commercial-grade drivetrain built for decades of service
The DIY battery bank alone is worth studying. Building a 26kWh system from recycled scooter cells is an impressive feat of engineering that saved thousands compared to buying new lithium batteries. The rig sleeps two adults and a toddler, and the builder is a healthcare worker and travel nurse — proof that full-time vehicle living works even with demanding careers.

7. Een Bus Vol Avonturen — A Firetruck Home for a Family of Six

Karlijn Dresscher and her family of six — two adults and four children — live full-time in a converted Mercedes-Benz 1113 firetruck. The Dutch family’s name, “Een Bus Vol Avonturen,” translates to “A Bus Full of Adventures,” and they’ve certainly lived up to it.
- Family of six living full-time in a converted firetruck — one of the largest families we’ve seen in a vehicle conversion
- Two sleeping areas: bunk beds for the kids plus a pop-top parents’ room for privacy
- Outdoor kitchen that keeps cooking smells and heat outside the living space
- Wood stove for heating — a cozy choice for European winters
- Published a book about their journey (ISBN 9789464895506)
What makes this build truly special is the proof of concept: a family with four kids can live comfortably in a converted firetruck. The bunk bed and pop-top combination solves the sleeping puzzle, and the outdoor kitchen is a clever space-saving solution that most vehicle dwellers eventually wish they had.

Why Ambulances and Firetrucks?
These emergency vehicles share several advantages over more common conversion platforms:
- Built to survive: Emergency vehicles are constructed to higher standards than consumer vehicles, with reinforced frames and commercial-grade components
- Standing height: Most ambulances offer 6’+ ceilings right out of the box — no roof raise needed
- Affordable entry: Retired units often sell at auction for $3K-$15K, significantly less than many conversion vans
- Existing infrastructure: Many come with shore power hookups, lighting circuits, and storage compartments already installed
- Insulation: Ambulance patient compartments are typically already insulated and climate-controlled
Which Build Inspires You?
From Tom’s museum-quality walnut cabinetry in The Lost Box to Karlijn’s firetruck home for six, each of these builds takes a completely different approach to the same starting point. Whether you’re drawn to the budget-friendly $3K auction ambulance or the two-story pop-top firetruck, there’s something here for every kind of adventurer.
