This morning, a highly anticipated RV finally started reaching customers: the Wingamm Oasi 540.1. This ultra-compact motorhome promises to be a game-changer. It’s shorter than many half-ton pickup trucks and designed to handle like a car, yet its interior rivals that of a camper van. After four long years of waiting for its U.S. debut, the Wingamm Oasi 540.1 is finally here, with deliveries already underway.
A Long Time Coming
The news is even better than the initial announcement. Wingamm actually started deliveries this month, with coaches being delivered to their owners after the 2025 Florida RV SuperShow. The company is now ramping up production with more shipments expected throughout this year and beyond. The delivery schedule has been a bit unconventional, but the story behind it is intriguing.
The coaches are built in what might seem like an inefficient manner, but there’s a good reason for it. Wingamm celebrated crossing the finish line after a development timeline that had some worried the project wouldn’t happen. I got a chance to see the units you can buy right now, and I like a lot of what’s going on with them.
The Trend Towards Smaller RVs
There’s a growing disenchantment with the enormous buses that often dominate campgrounds. While large RVs are a classic symbol of the American road trip, a new breed of RV is challenging that dominance.
Over the past four years of covering RVs, I’ve noticed a trend: many people don’t want to drive a massive vehicle, deal with the high fuel costs, or manage the space a huge RV requires. A growing number of Americans want an RV that’s spacious but still fits into a standard parking spot.
In essence, people are looking for the mythical “TARDIS” of RVs. Sure, you could opt for a camper van, but some might argue they don’t offer enough space. Stepping up to a Class C RV makes things bigger, but for some, it’s still too much.
Europe has long had a solution to this problem. While RVs in Europe can get quite large, most seem like quaint cottages compared to the behemoths American retirees drive, often on standard licenses. A number of companies have realized that Americans are ready for an alternative to the big, boxy, and often boring RVs sold in the U.S., and Wingamm is bringing that alternative here.
The Americanized Oasi 540.1
The Oasi 540.1 is the American adaptation of the successful 540 coach already popular in Europe. Converting a European RV to meet U.S. standards proved to be more complicated than expected.
Wingamm initially announced its U.S. entry in early 2021, with a projected launch later that year. However, the launch date was missed multiple times. The American version has effectively been in development for much of my writing career. Then, in May 2024, I reached out to Wingamm to get an update. I was told the launch was happening “soon.” “Soon” turned out to mean January 2025. But hey, we live in a world where startups make big promises and don’t always deliver!
Overcoming Challenges
A series of setbacks plagued Wingamm in 2021. The company cited COVID-19 supply chain issues, particularly parts shortages from Stellantis, which manufactures the Ram ProMaster in Mexico. This slowed down development. Then, when the cutaways finally reached Italy, Wingamm’s U.S. parts suppliers faced their own pandemic-related problems, preventing them from finishing the test coaches.
Wingamm had to source numerous significant parts, including plumbing, from new suppliers before completing prototype vehicles.
While this was happening, Wingamm imported a European-spec Oasi 540 into the U.S. for demonstration at RV shows. This allowed the company to gather feedback on what needed to be changed for the American market.
I first saw the Oasi 540 at the 2023 Florida RV SuperShow, where it was a real head-turner. The coach was based on an Italian-market Fiat Ducato, not a Ram ProMaster. Its engine was a 2.3-liter Iveco F1A diesel, producing 175 HP. The interior also reflected the European design.
Adapting for the American Market
Despite those differences, the public at the 2023 show was captivated. They loved the Oasi’s compact 17-foot, 6-inch footprint combined with its surprisingly spacious interior.
The Oasi 540 is shorter than many large camper vans and smaller than many half-ton pickup trucks. Yet, it also has an interior with room to spread out like a Class C RV.
Sadly, the Oasi 540 show vehicle was imported purely for display purposes, wasn’t road-legal, and had to be returned to Italy. However, the feedback from that show was invaluable in helping the company tailor the Oasi 540.1 to the needs of American buyers.
Wingamm then needed to address the situation that the vehicles needed to be shipped from Mexico to Baltimore, then from the port to Italy for completion, after which they were sent back to the U.S. The RV also needed to be certified by the authorities, taking four years in total.
An Unusual Shipping Process
The shipping process is somewhat unusual. Stellantis ships the ProMasters to Boston or Baltimore, and then Wingamm covers the cost of shipping the cutaways to Italy for completion before they are sent back to the U.S. Wingamm says that the ultimate solution would be building the one-piece fiberglass RV bodies in America, but it wants to ensure the quality of any company it partners with.
What to Expect in the Oasi 540.1?
Let’s take a closer look at what Americans will get when they purchase an Oasi 540.1. The front of the Wingamm is attached to a Ram ProMaster cutaway chassis. The Oasi 540.1 features a 3.6-liter Pentastar V6 engine producing 276 HP, driving the front wheels through an automatic transaxle.
The Wingamm’s signature fiberglass and polyurethane monocoque is attached to the back of that cab. Wingamm says the one-piece fiberglass construction gives it superior insulation. It also minimizes potential water leak points and prevents squeaks. Unlike some designs, there is no metal in the body; a sandwich of two fiberglass panels with polyurethane foam provides insulation.
Customer feedback led to several improvements. The old small sliding window was replaced with a larger Dometic window, European-style entry steps were replaced with a stronger version, and the entry door received an update for ease of operation. Also, there is now a grab handle at the entryway. Other improvements include a better-latching propane tank compartment and a largely unchanged storage setup. The RV’s waste tank features a 5-gallon cassette. At RV shows, opinion on the waste tank was split. It is easy to dump, but fills up fast. The magic truly happens inside the Oasi 540.1.
Interior Design
Stepping inside, you’ll be surprised at how much space Wingamm has managed to fit into a footprint smaller than a half-ton truck. You won’t be cramped. The Oasi 540.1 feels like you’re walking inside a Class C coach, even though its footprint is more compact.
Changes include the cooktop and sink, which have been updated, as has the location of the stereo speakers for a cleaner look. The materials are high-quality, with Rubelli fabrics for seating and curtains, Brivio Italian poplar plywood for counters, Arpa Ker Laminates, and Kaindl Optimatt laminates for cabinets and walls. The furniture is bonded to the fiberglass structure rather than screwed in, preserving structural integrity and eliminating squeaks.
The Wingamm has two beds. The dinette retracts and converts into a bed for two. You can also lower a large bed from the ceiling. That ceiling bed can hold up to 770 pounds and has its air vents.
I particularly like the bathroom. Though it’s a wet bath, it’s configured in a way that makes it feel like a normal bathroom. The bathroom is so spacious that I was able to take a bathroom selfie.
The Oasi 540.1 comes equipped with air conditioning, a 26-gallon water tank, and plenty of kitchen space. Heating is provided by a traditional RV heater and a radiant floor heat system. Power is supplied by two AGM batteries with 95 Ah each. Those batteries link with a BOS LE300 322 Wh lithium battery to create a hybrid house battery system. The LE300 extends the lifespan of the AGM batteries. You can also option your Oasi 540.1 to have two lithium batteries. The coaches also come with 210W of roof solar. The curb weight is 6,062 pounds.
Options and Availability
Currently, there are three versions of the Wingamm Oasi 540.1 available. The standard model is all-white with stone-like interior accents; the Fashion Edition has exterior graphics and a white interior; and the Black Edition is like the standard model, but with black graphics.
When Wingamm first announced its American entry, it was said the price would be around $145,000. After modifications and certification, the price was revised to $188,500. The production Wingamm Oasi 540.1 is now selling for that price.
That is still a lot of money, of course. However, the Wingamm Oasi 540.1 presents a compelling alternative to a luxury van. Consider that a Winnebago Sprinter with a cheap plastic interior goes for $254,000. Even the Airstream Interstate 19 costs $228,900.
If you’re considering spending $200,000 on a camper van, it may be worth it to look at the Wingamm. It has more storage, more room to spread out, a better bathroom, and a smaller footprint.
Wingamm anticipates building fewer than 100 units for the U.S. market this year due to factory limitations, which will limit the number of vehicles produced in the U.S. But according the company, more units are on the way in March.
Wingamm’s dealer and service network is still being developed. The company is also planning larger models, including the 610 and 690, which have more significant storage compartments. If everything proceeds to plan, the larger models may arrive around 2026.
The Wingamm Oasi 540.1 is finally available. Its compact size and car-like handling make it appealing, with some owners using it like an MPV, as a camper on the weekend and for everyday use during the week. Time will tell if this concept will be successful.
