Recreational Vehicles (RVs) Under Washington Lemon Law
How Washington's Lemon Law applies to motor homes — chassis coverage under RCW 19.118 vs. living-quarters coverage.
Washington’s Lemon Law covers the self-propelled chassis portion of motor homes under RCW 19.118.021 — but excludes the living-quarters portion. This is the same approach used in Florida and most other states.
What’s covered
- Chassis defects — engine, transmission, brakes, steering, suspension, electrical, fuel system.
- Chassis-mounted safety systems.
- Drivetrain components.
What’s NOT covered
- Coach / living-quarters defects — slide-outs, leveling jacks, refrigerator, water systems, awnings, generator (when not chassis-mounted), HVAC for the living area, furniture, electrical for the living area.
For coach defects, consumers turn to:
- Coach builder warranty (typically 1 year / 12,000 miles or 24,000 miles).
- WCPA — for misrepresentation claims (treble damages capped $25K/violation).
- Magnuson-Moss — federal-court access for warranty breach claims.
Class A, B, and C motor homes
The chassis-only Lemon Law coverage applies the same way across all classes:
- Class A (full motor home) — chassis covered.
- Class B (van conversion) — chassis covered.
- Class C (cab-chassis with coach) — chassis covered.
Travel trailers and fifth-wheels
Towable RVs (travel trailers, fifth-wheels) are typically NOT covered under RCW 19.118 because they are not “motor vehicles.” Towables fall under WCPA and Magnuson-Moss only.
Pacific Northwest RV market
Washington has substantial RV market share — particularly for:
- Pacific Northwest tourism (Olympic Peninsula, San Juans, Cascades).
- Forest-service / state-park camping.
- Snowbird migration (winter southbound to Arizona / Southern California).
Chassis defects we see
- Workhorse / Freightliner chassis electrical and brake issues.
- Ford F-53 motorhome chassis transmission and steering defects.
- GM chassis powertrain issues.
Bottom line
Motor home chassis defects get full Washington Lemon Law protection. Coach / living-quarters defects fall under WCPA and Magnuson-Moss only — meaningful protection, but without the Lemon Law’s refund/replacement mechanic. Travel trailers and fifth-wheels are excluded from the Lemon Law but covered by WCPA and Magnuson-Moss.
