Below you’ll find Winnebago-specific WMI codes, an explanation of why many Winnebago VINs actually start with a chassis manufacturer’s code instead of Winnebago’s own, a position-by-position guide to reading the VIN, where to find the VIN on an RV, and how to check for open recalls.

About Winnebago

Winnebago Industries was founded in Forest City, Iowa, in 1958 (originally as Modernistic Industries) under local businessman John K. Hanson, who took over the struggling trailer plant and renamed it Winnebago Industries in 1961. Hanson vertically integrated production, building components in-house rather than buying from suppliers, which let Winnebago undercut competitors and made it the dominant name in American RVs through the 1960s and 70s. Forest City remains Winnebago’s principal motorhome campus today. The company is now a multi-brand outdoor recreation group that also owns Grand Design (towables, Middlebury, Indiana), Chris-Craft and Barletta (boats), and Newmar (acquired 2024). This page focuses on motorized Winnebago and Itasca-badged motorhomes and camper vans, the segment a VIN decode needs to untangle.
The single most important thing to understand about a Winnebago VIN is that motorhomes are built in two stages, and the VIN’s first three characters (the WMI) reflect whoever built that stage. A chassis manufacturer, Ford, Freightliner Custom Chassis Corporation (a Daimler Truck division), Mercedes-Benz, or Stellantis/Ram, builds and VINs a bare or cutaway chassis first. Winnebago, as the “final-stage” or “second-stage” manufacturer, then builds the coach body onto it. Under federal rules, the VIN assigned at the incomplete-vehicle stage generally stays with the vehicle through completion, so the WMI on the title often belongs to the chassis maker, not Winnebago, even though “Winnebago” is the brand on the outside:

• Class B camper vans (Travato, Solis, Solis Pocket) ride on a Ram ProMaster chassis; WMI belongs to Ram/FCA US.
• Class B diesel vans (Revel) ride on a Mercedes-Benz Sprinter chassis; WMI belongs to Mercedes-Benz/Daimler.
• Class C motorhomes (Ekko, Navion, Itasca cutaway models) typically use a Ford or Mercedes Sprinter cutaway; WMI traces to Ford or Mercedes.
• Class A gas motorhomes commonly use a Ford F-53 stripped chassis, WMI’d by Ford.
• Class A diesel motorhomes typically ride on a Freightliner Custom Chassis Corporation (FCCC) platform, WMI’d by Freightliner.
• Select Winnebago coach-built vehicles, where Winnebago itself is the vehicle manufacturer of record with NHTSA, use one of Winnebago’s own WMIs (below).

If a decoded Winnebago-badged RV comes back “Ford,” “Mercedes-Benz,” “Ram,” or “Freightliner” instead of “Winnebago,” that’s expected. You’re reading the chassis-stage WMI, and the decoder can still surface Winnebago coach details from the rest of the VIN and the vehicle’s data plate.

Winnebago WMI codes (positions 1–3)

The first three characters of a VIN, the World Manufacturer Identifier (WMI), are assigned by SAE International and registered with NHTSA. Per NHTSA’s vPIC database, Winnebago Industries, Inc. holds these WMIs:

For comparison, here are the WMIs of the chassis manufacturers whose codes appear most often on Winnebago-badged motorhomes:

If your VIN starts with one of the chassis codes above rather than 1WV/1WW/1WT, that’s normal for the model, see the section above for why.

How to read a Winnebago VIN: position by position

Motorhomes built since the early 1980s follow the same ISO 3779 17-character VIN standard used across the auto industry. The 17 characters split into three blocks:

Positions 1–3: World Manufacturer Identifier

See the WMI tables above. Remember: this identifies who built and VIN’d that stage of the vehicle, which on many motorhomes is the chassis OEM, not Winnebago.

Positions 4–8: Vehicle Descriptor Section (VDS)

On chassis-stage VINs (Ford, Freightliner, Mercedes, Ram), these positions describe the chassis model, GVWR class, engine, and brake/restraint system, not the Winnebago coach model. A Winnebago RV’s specific floorplan, coach length, and interior configuration aren’t fully recoverable from the VIN alone; they’re recorded on Winnebago’s own build sheet and RVIA certification label, which is why decoding is best paired with the coach’s serial number.

Position 9: Check digit

The check digit is calculated from the other 16 characters using a fixed weighting formula and modulo-11 math, exactly as on any other vehicle. If a single character is mistyped or misread off a weathered decal, the check digit won’t validate.

Position 10: Model year

The 10th character maps to a model year on a repeating 30-year cycle, identical across all manufacturers:

The letters I, O, and Q are never used in any VIN, because they can be confused with the digits 1 and 0.

Position 11: Assembly plant

Identifies the specific factory that built that stage of the vehicle: a Ford, Freightliner, Mercedes, or Ram plant for the chassis, or a Winnebago Forest City, Iowa facility for coach-stage WMIs.

Positions 12–17: Serial number

The production sequence number for that specific vehicle at that plant. Winnebago’s own systems also track vehicles by a separate coach serial number printed on the certification label, keep both numbers handy when ordering parts or requesting service records.

Where to find the VIN on a Winnebago

Because a motorhome carries at least two identity labels, one for the chassis, one for the coach, check all of the following:

• Chassis VIN plate: driver’s side door frame or door latch post (Ford, Ram, and most cutaway chassis), visible through the windshield on the dashboard, or a plate near the radiator/frame rail on Freightliner chassis
• Federal certification/compliance label: Winnebago’s coach-level label, typically on the front lower portion of the driver’s door, the wall beside the driver’s seat, or the pillar forward of the driver’s door, the label Winnebago itself points owners to
• Winnebago serial number tag: often a separate plate or sticker inside a cabinet or storage bay, used by Customer Care and parts lookup
• Vehicle title, registration, and insurance documents

If your Winnebago is a vintage unit from the 1960s or 70s (the era of the boxy, “flying W”-badged Brave, Indian, and Chief models built on Dodge and other OEM chassis), the VIN format predates the 17-character ISO standard and will be shorter and non-standard. For those pre-1981 coaches, use our classic car VIN decoder guide.

Check Winnebago recalls and safety information

Recalls on a Winnebago-badged RV can be issued by either Winnebago (coach items like wiring, hood brackets, or slide-outs) or by the chassis OEM, Ford, Freightliner, Mercedes-Benz, or Ram (chassis, brake, or engine items), since both are legally distinct manufacturers on the same unit. To check a specific VIN:

1. Decode the VIN above to confirm the model, model year, and which WMI applies
2. Check Winnebago’s own lookup at winnebago.com/owners/owner-resources/recalls for coach recalls, and NHTSA’s recall search for both coach and chassis recalls
3. If the recall traces to the chassis, contact that manufacturer’s dealer network directly, chassis recall repair is administered separately from Winnebago’s
4. Schedule the free repair at an authorized service center

Recent examples confirm this dual-authority pattern: Winnebago issued recall 24V-733 covering multiple model years of Tour, Journey, Forza, Brave, Grand Tour, Vista, Adventurer, Sightseer, and Itasca motorhomes for undersized turn-signal lenses, and recall 24V-826 for hood mounting brackets, both administered directly by Winnebago as coach-level issues. Recalls are repaired free of charge regardless of the vehicle’s age or ownership history.

Frequently asked questions

How do I decode my Winnebago VIN?

Type the 17-character VIN from your motorhome’s driver-door frame, dashboard, or federal certification label into the decoder at the top of this page. Results return in seconds and include model, model year, chassis type, and recall status. No registration is required.

Why does my Winnebago’s VIN start with a Ford, Mercedes, or Ram code instead of Winnebago’s own WMI?

Because most motorhomes are built in two stages. The chassis manufacturer, Ford (F-53/E-Series), Freightliner Custom Chassis Corp. (diesel Class A), Mercedes-Benz (Sprinter-based Revel and Ekko), or Ram (ProMaster-based Travato and Solis), VINs the rolling or cutaway chassis first, and that VIN generally stays with the vehicle after Winnebago completes the coach as final-stage manufacturer. Winnebago Industries does hold its own WMIs (1WV, 1WW, 1WT), but a large share of current motorhomes decode to the chassis OEM instead. That’s normal, not an error.

Where is the VIN on my Winnebago motorhome?

Check the driver’s side door frame or latch post and the dashboard (visible through the windshield) for the chassis VIN, and the federal certification label, usually near the driver’s door or entry step, for Winnebago’s own coach identification. Many owners also find a separate serial number tag inside a cabinet or storage bay.

Is the Winnebago VIN decoder free?

Yes. VinDecoderPlus decodes every Winnebago VIN free of charge with no sign-up or credit card. Full vehicle history reports, including ownership records, accident history, and odometer history, are available as an optional paid upgrade.

What does the VIN tell me about my Winnebago?

A VIN decode identifies the chassis manufacturer, model year, and body/chassis class, plus any open recalls tied to that VIN, whether issued by Winnebago or the chassis OEM. It doesn’t capture the specific floorplan, interior package, or factory options, which live on Winnebago’s build sheet and certification label rather than in the VIN itself.

Can a Winnebago VIN be faked or cloned?

The 17 characters can be retyped or misrepresented, but the check digit at position 9 makes silent tampering hard to hide: any single-character change breaks the math. Because a motorhome carries both a chassis VIN and a Winnebago serial number, comparing the two against the title and certification label is a useful extra cross-check. If you suspect a cloned VIN, our guide how to check if a car is stolen by VIN walks through the next steps.
