Double Decker RV: Do They Exist and What Do They Cost?

Double decker RVs do exist, but they are almost exclusively custom-built or high-end European imports. In 2026, companies like Anderson Mobile Estates continue to lead the luxury market with multi-story trailers that use massive hydraulic lift systems to create a second floor. For a more “attainable” “double decker rv” experience, many DIYers are converting retired Neoplan or Bristol VRT buses into stationary Airbnbs or mobile homes, offering nearly 800 square feet of living space across two levels for a fraction of the cost of a new Class A motorhome.

There are also purpose-built two-storey motorhomes – the most famous being the Prevost H3-45 with slide-out expansions that create an almost house-like interior – and toy haulers with roof terraces that give a partial second level experience without the complexity of a true two-storey structure.

What Is a Double Decker RV?

A double decker RV is any recreational vehicle featuring two distinct living levels – typically a ground floor with kitchen, bathroom, and lounge, and an upper level used as a bedroom, entertainment area, or observation deck.

Unlike standard motorhomes that maximise living space through slide-outs within a single-storey layout, double decker designs stack space vertically. This makes them dramatically taller than conventional RVs – often 13 to 15 feet in height – which creates significant clearance challenges on bridges, trees, and highway structures.

Do Double Decker RVs Actually Exist?

Yes – but they are custom builds rather than showroom purchases. No major RV manufacturer currently sells a true two-storey motorhome as a production model. Every double decker RV you see online or in a viral video is either a converted vehicle (bus, truck, shipping container) or an extremely high-end custom commission.

The closest thing to a production double decker RV are high-end bus conversions from companies like Prevost, MCI, and Marathon Coach – but these are technically single-level coaches with extremely tall interiors, not true two-storey designs.

Famous Double Decker RVs

Types of Double Decker RVs

Converted Double Decker Buses

The most popular and accessible route to a double decker RV. Vintage or decommissioned double decker buses – particularly UK AEC Routemasters or modern Volvo coaches – are purchased and converted by specialist builders or adventurous DIYers. The conversion typically involves insulating both decks, installing plumbing and electrical systems, building a kitchen and bathroom on the lower deck, and converting the upper deck into sleeping quarters or a lounge.

A basic self-conversion of a purchased bus can be done for $30,000 to $80,000 in materials and labour. Professional builds from specialist companies start around $150,000 and scale to $500,000+ for high-end finishes.

Custom-Built Two-Storey Motorhomes

True purpose-built two-storey motorhomes are extraordinarily rare and eye-wateringly expensive. These are commissioned from specialist coachbuilders – primarily in the US and Germany – and involve designing an entirely bespoke vehicle from the ground up. Build costs typically start at $500,000 and can reach $2 million or more for flagship one-off commissions.

Toy Haulers with Roof Decks

A more practical and legally simpler alternative, some toy hauler trailers now feature factory-installed rooftop decking and staircases – giving occupants a genuine outdoor upper-level space without the engineering complexity of a true second storey. These are available from $80,000 to $150,000 from manufacturers like Keystone and Grand Design.

Legal Considerations – Height Limits and Road Rules

This is where double decker RV ownership gets complicated. Most US states impose a maximum vehicle height of 13 feet 6 inches (4.1 metres) for vehicles without special permits. A true double decker will almost always exceed this, meaning you need oversize load permits to drive on many roads – and certain routes, particularly those with low bridges, tree coverage, or tunnel restrictions, will be completely inaccessible.

In the UK, where double decker buses are common, converted RVs still need to meet DVLA height regulations and pass engineering inspections. The rules vary significantly by country, so legal research specific to your region is essential before beginning or purchasing any double decker build.

Frequently Asked Questions

Can I buy a double decker RV at a dealership?

No major RV dealership sells production double decker motorhomes. You would need to commission a custom build, purchase a converted bus privately, or work with a specialist conversion company.

What is the tallest road-legal RV you can buy?

Most production motorhomes top out at 12 feet 6 inches to 13 feet. The Prevost H3-45 and Marathon Eagle conversions reach 12 feet 8 inches – staying within legal limits for most US highways while providing the tallest possible interior without permit requirements.
