Wisconsin RV sales follow the standard DMV vehicle process: title, MV1, MV2872 bill of sale, 30-day deadline, 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.
Motorhomes title like motor vehicles; towable trailers title like trailers — and the paperwork differs for each. Our guide covers lien holder procedures, what to do with an active loan balance, and how RV registration deadlines work. Read: Car Bill of Sale: Complete Guide →

Title Required
Yes
RVs, motorhomes, travel trailers, fifth-wheels, and pop-ups all require Wisconsin titles. Motorhomes (Class A/B/C) are titled and registered as motor vehicles. Travel trailers and fifth-wheels are titled as trailers and require their own registration. Buyer files Form MV1 within 30 days. Federal odometer disclosure applies to motorized RVs less than 20 model years old.
Inspection
Not required
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: Family transfers (spouse, parent, child, sibling, grandparent, grandchild) are exempt with documentation. Gifts are exempt. 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)
Form MV2872 bill of sale: VIN, year/make/model, length, sleeps, sale price, included equipment
Buyer files Form MV1 with WisDOT DMV within 30 days; 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

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 — DMV checks NADA RV values, and a $5,000 sale of a 2023 Class A will get flagged
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 30-day MV1 deadline — same $50 late title transfer fee 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 30 days, 5%-plus tax at the counter, and itemize the systems in writing.
Wisconsin RV Bill of Sale — FAQs
Do I need to title both the RV and the truck I tow it with in Wisconsin?
Yes — separately. A travel trailer or fifth-wheel is its own titled vehicle in Wisconsin and needs its own MV1 application, $164.50 title fee, and trailer registration. The tow vehicle (truck or SUV) keeps its own title and registration. A motorhome combines chassis and living quarters into a single titled motor vehicle and is registered under the auto class. If you sell or buy an RV-and-tow-vehicle pair, you need two bills of sale and two MV1 filings.
How is sales tax calculated on a Wisconsin RV purchase?
Wisconsin charges 5% state sales tax on the actual purchase price plus 0.5% county tax in most counties and a 0.5% local stadium-area tax in Milwaukee, Ozaukee, Racine, Washington, and Waukesha counties. The full price including factory options, generator, awning, and any included accessories is taxable. DMV uses NADA RV values to check unrealistically low sale prices. On a $60,000 used Class C, expect $3,000–$3,300 in sales tax at the DMV counter on top of title and registration fees.
Does my motorhome need a Wisconsin emissions test?
Only in the seven southeastern emissions counties — Milwaukee, Waukesha, Kenosha, Ozaukee, Racine, Sheboygan, and Washington — and only if the motorhome is gasoline-powered, model year 1996 or newer, and rated under 14,000 lbs GVWR. Most Class A motorhomes exceed 14,000 lbs and are GVWR-exempt. Diesel pushers are exempt. Class B vans and small Class Cs under 14,000 lbs GVWR in those seven counties do need a biennial emissions test. Travel trailers and fifth-wheels have no engine and are never tested.
Should a Wisconsin RV bill of sale include the generator and appliances?
Yes, in detail. List the generator make/model and hours, refrigerator type (absorption vs. residential), furnace, water heater, A/C units, slide-outs, awnings, satellite, solar, and inverter. RV buyers expect more disclosure than car buyers because RVs have many more systems, and Wisconsin's buyer-beware private-sale rules mean any system you fail to disclose problems with becomes the buyer's problem. Disclosing known issues honestly on the bill of sale is also the strongest protection against later fraud claims.
Can I drive an RV home from a private sale before titling it?
You need a temporary operating permit from WisDOT DMV — Wisconsin plates stay with the seller, so the RV cannot legally drive on the seller's plates after the sale. A 90-day temporary plate ($3) at any DMV service center, with the assigned title, MV2872 bill of sale, and proof of insurance, lets you drive the RV home and complete the MV1 title application within the 30-day window. For non-motorized travel trailers and fifth-wheels, a temporary plate is also available, and the trailer can typically be towed on the truck's plates if the truck is registered.
