Grand Design Unveils Omega Frame While Federal Investigation and Class-Action Lawsuit Continue

Grand Design has announced the new Omega fifth wheel frame, a redesigned chassis built with thicker steel, more fasteners, and added structural supports. The frame comes on Reflection, Solitude, Influence, and Momentum models and arrives with a five-year limited warranty that applies retroactively. That alone is a notable shift.

The announcement landed only months after a federal investigation was opened into reported structural issues on earlier Grand Design units, and as a class-action lawsuit moves forward. Grand Design has not stated that the new Omega design is a response to either, but the overlap has raised questions among owners who have followed the developments closely.

What is the Omega Frame?

The Omega design adds stronger outriggers, larger gussets, reinforced side plates, and extra crossmembers in targeted areas. Grand Design says the layout was developed with third-party automotive engineers who focused on high-stress points where earlier frames showed the greatest load. The company positions the Omega frame as a step toward better long-term stability and fewer structural failures over the life of the trailer.

So what does this mean for current owners? Based on publicly available information, the Omega frame applies only to new production. There has been no announcement suggesting retrofits or upgrades for earlier models.

Federal Investigation and Lawsuit Still Under Way

Months before the Omega frame announcement, the National Highway Traffic Safety Administration opened a preliminary evaluation into reports of excessive frame flex on certain Grand Design units. The case, PE24-029, includes an estimated 55,887 Momentum and Solitude fifth wheels built between 2017 and 2023. One injury and multiple complaints of flexing and doors opening during travel appear in the public filing. The investigation is active and no recall has been issued at this time.

In April 2025, a class-action lawsuit was filed by Weitz & Luxenberg P.C. alleging structural defects and warranty concerns on specific models. The case is ongoing and no court findings have been issued.

Both the federal investigation and the class-action lawsuit involve prior frame designs on older fifth wheel models. Grand Design has not stated that the new Omega design is a response to either action, but the timing has led some owners to ask questions about the relationship.
