Free Wisconsin RV Bill of Sale
Wisconsin RV sales follow the standard DMV vehicle process: title, MV1, an optional bill of sale, a two-business-day title-and-registration window if the RV will be operated, and 5%-plus sales tax at registration. Motorhomes are titled and registered as motor vehicles; travel trailers and fifth-wheels are titled and registered as trailers. Wisconsin's big GVWR motorhomes (over 14,000 lbs) escape the SE Wisconsin emissions test. Document propane systems, generators, slides, and any factory recall or warranty status — RV buyers care about the systems as much as the chassis.

Wisconsin RV Bill of Sale — What You Need to Know
Sales Tax Details
5% Wisconsin state sales tax plus 0.5% county tax (and 0.5% stadium-area tax in Milwaukee, Ozaukee, Racine, Washington, and Waukesha counties) applies to RV and trailer purchases. RVs are taxed on the full purchase price including any "extras" (generators, awnings, slide-outs, satellite). Tax collected by DMV at titling.
Exemption: Transfers between qualifying close relatives can be exempt; confirm with WisDOT which relationships qualify. Trade-in credit is only available at licensed dealers, not private sales.
Inspection Requirements
Wisconsin has no statewide RV safety inspection. Motorhomes registered in the seven southeastern emissions counties (Milwaukee, Waukesha, Kenosha, Ozaukee, Racine, Sheboygan, Washington) are exempt from emissions testing if over 14,000 lbs GVWR or diesel — most Class A and many Class C motorhomes qualify for the GVWR exemption. Travel trailers and fifth-wheels never need emissions testing.
Registration
Registration for this vehicle type is handled by Wisconsin DMV — not the same agency that handles cars in Wisconsin. Plan for separate filings.
Wisconsin RV Sale — Step-by-Step Checklist
- Title properly assigned with seller signature, buyer info, sale price, and odometer (for motorized RVs <20 model years old)
- Bill of sale (optional in Wisconsin): VIN, year/make/model, length, sleeps, sale price, included equipment
- Buyer files Form MV1 with WisDOT DMV within two business days after purchase if the RV will be operated; pays $164.50 title fee + registration
- DMV collects 5% state tax + 0.5% county tax (+ 0.5% stadium tax in 5 SE counties) on full purchase price
- Disclose generator hours, propane system condition, slide-out function, roof condition, water damage history
- Provide all keys, owner's manuals, appliance warranties, and any factory recall paperwork
- For travel trailers/fifth-wheels: also document tongue weight, GVWR, axle ratings, and brake controller compatibility
Common Pitfalls
- Forgetting that travel trailers and fifth-wheels need their own Wisconsin title separate from the tow vehicle
- Underreporting the price to dodge tax — the price sets the 5% sales tax, and misreporting it is tax fraud
- Not disclosing soft floors, roof leaks, or delaminated walls — these are the most common RV defects and Wisconsin's "as-is" doctrine doesn't cover active concealment
- Missing the two-business-day MV1 window for an RV that will be operated — the same WisDOT timing rule as cars
- Assuming an emissions exemption for a Class C motorhome — under 14,000 lbs GVWR Class Cs in the SE emissions counties still need a passing test
Pro Tip
RVs in Wisconsin are titled vehicles like any car, with the added wrinkles of motorhome-vs-trailer registration, GVWR-based emissions exemptions in the SE counties, and a longer disclosure list. MV1 within two business days if the RV will be operated, 5%-plus tax at the counter, and itemize the systems in writing.
