Mobile homes, recreational vehicles, boats and other trailers

Vehicle definitions

Manufactured homes 1976 and newer exceeding 40 feet, or 1975 and older exceeding 45 feet, are handled by the Department of Safety and Professional Services (DSPS). These units were originally titled by the Wisconsin Department of Transportation (WisDOT) in the past but have been handled by DSPS since 2001.​

For manufactured homes, mobile homes and non-collapsible recreational vehicle trailers, send the title and registration application to either DSPS or WisDOT - depending on the vehicle type, model year and length of the vehicle. See table below:​​

Manuf
actured/mobile homes or recreational vehicles

Manufactured and mobile homes greater than 45 feet long, except for fifth wheel, travel trailers or park model RV trailers, are exempt from registration. Manufactured and mobile homes must be titled.

The temporary undercarriage on which a manufactured/modular home is transported does not need to be titled, but during operation on a public road, it must display a Transferable Trailer​​ license plate registered to the transporter. (See applying for title and registration.) The transferable trailer plate should be applied for at the weight sufficient to cover the total weight of the undercarriage plus the load.

Camping or pop-up trailers

A title and registration is not required for collapsible camping trailers at or less than 3,000 pounds gross weight unless they are used for hire or rental. Title and registration is encouraged for vehicles that will be used on roads outside the state of Wisconsin, as other states' registration laws may be different.

​A title and registration is required for trailers operated over 3,000 pounds. A title and registration is not required for trailers operated at or less than 3,000 pounds gross weight unless used for hire or rental. Title and registration is encouraged for these vehicles that will be used on roads outside the state of Wisconsin, as other states' registration laws may be different.
