Recreational Vehicles (RVs) Under Massachusetts Lemon Law
Motor homes are excluded from § 7N½ — but Chapter 93A and Magnuson-Moss remain available for RV defects.
Massachusetts excludes motor homes from § 7N½ coverage. This is materially different from Washington, Florida, and most other states, which cover the chassis portion of motor homes.
What’s NOT covered under § 7N½
- Motor homes (Class A, B, and C) — fully excluded.
- Travel trailers — not “motor vehicles” under the statute.
- Fifth-wheels — same.
What IS covered
- The chassis portion through manufacturer’s chassis warranty — but enforcement is through general warranty law, not § 7N½.
- Coach builder warranty — typically 1 year / 12,000 miles.
What fills the gap
For RV defects, consumers turn to:
- Chapter 93A § 9 — 4 years from accrual; mandatory § 9(3) demand letter; double/treble damages on willful/knowing or inadequate tender; mandatory § 9(4) fees.
- Magnuson-Moss Warranty Act — federal-court access for written warranty claims.
- Implied warranty of merchantability (M.G.L. c. 106, § 2-314).
Common RV defect categories
Chassis defects
- Workhorse / Freightliner chassis electrical and brake issues.
- Ford F-53 motorhome chassis transmission and steering defects.
- GM chassis powertrain issues.
Coach defects
- Slide-out failures.
- Leveling jack failures.
- Refrigerator (RV-specific absorption refrigerators) failures.
- Water system leaks.
- Awning failures.
- Generator failures.
Chapter 93A as the primary tool for MA RV cases
Because Massachusetts excludes RVs from the Lemon Law, Chapter 93A becomes the primary statute for serious RV warranty disputes. The § 9(3) demand letter framework applies, and inadequate manufacturer tender triggers mandatory doubling/trebling plus mandatory § 9(4) fees — even though the Lemon Law itself doesn’t apply.
Federal-court strategy
D. Mass. provides federal-court Magnuson-Moss venue for RV warranty cases, particularly useful for high-value Class A motor homes.
Bottom line
Massachusetts is unusually restrictive on RVs — § 7N½ doesn’t apply. But the strong Chapter 93A framework (mandatory § 9(4) fees, double/treble damages on willful or inadequate § 9(3) tender) plus Magnuson-Moss federal-court access make Massachusetts a meaningful jurisdiction for RV defect claims despite the Lemon Law exclusion.
