Yes, many states’ lemon laws apply to the motor vehicle portion of RVs, campers, and motor homes. This means the laws apply to defects affecting the chassis and drivetrain. But if your RV has a leaky shower, that typically won’t be covered by your state’s Lemon Law. However, the Lemon Law in some states applies to the full RV and will cover issues like a leaky shower.
Regardless of where you live or where you purchased your RV, the Magnuson-Moss Warranty Act applies to every component of a recreational vehicle. So, if your RV has any warrantied defect that the manufacturer fails to repair after a reasonable number of attempts, you deserve to be compensated according to the federal Lemon Law.
