Grand Design is addressing concerns of excessive frame flex or wall securement in the front upper deck area of a limited number of fifth-wheel units. This condition could potentially occur over time due to a combination of manufacturing variations, an overload condition, or hitch modifications. Wall securement or excessive frame flex does not compromise vehicle safety or structural integrity of the coach as verified by third-party experts. This service campaign covers 2020-2023 Grand Design Solitude and Momentum fifth wheel products that are 18,000lbs GVWR and over.
