the body structure

The Office of Defects Investigation (ODI) has received twenty-three complaints alleging excessive frame flex on model year 2017-2023 Grand Design fifth wheel recreational trailers, models Momentum and Solitude. Twenty-two of the complaints allege that excessive frame flex resulted in a cargo or entry door opening while in transit, some with objects lost on roadways, while six complaints also state that slideouts extended out partially. ODI has been in contact with both Grand Design and Lippert, the frame manufacturer. Grand Design believes that some frame flex, generally considered to be vertical movement in the upper deck area of the fifth wheel, is normal. However, Grand Design has developed a technical service bulletin (TSB), to evaluate concerns of excessive frame flex, defined as vertical movement greater than 3/8 inch. Per Grand Design, the frame flex is only occurring in the upper deck area of the fifth wheel and is resulting in cosmetic defects such as moving sidewalls, damage to cabinets, binding doors, etc. However, Lippert believes that the effects of frame flex may also extend back to the front axle of the trailer.While Lippert provides frames for multiple trailer manufacturers, the majority of complaints are for these Grand Design products. Cargo and entry doors that open and slideouts that extend while in transit increase the risk of injury or a crash. ODI is opening this Preliminary Evaluation (PE) to evaluate the severity of the potential problem and to determine whether an unreasonable risk to motor vehicle safety exists. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

Beginning in 2024 our RV exhibited consistent structural movement & frame flex including: upper deck flex, front cap cracking, cracked moldings, sidewall movement, filon transition movement, screws pushing upward into floors, slides coming out during travel.

Frame flex from broken welds on the pin box to the frame. It’s a very wide know thing across many GD models that used this same frame / pin box. I have pictures showing the angle of the pin box once weights applied, it’s a safety issue and there’s tons of people online having the same issue.

I am submitting a new safety complaint regarding my 2021 Grand Design Solitude 380FL, VIN [XXX] . On my first trip out this year (4/29/2026), while towing approximately 20 miles to a nearby campsite, the off-door-side cargo compartment door again opened during transit. As a direct result, a bucket containing my water hose, regulator, 90 degree fitting, etc were ejected from the compartment and onto the roadway at highway speed. This is a significant escalation of the safety issue previously reported. This is no longer limited to a door opening condition—this event resulted in unsecured cargo being discharged into a public roadway, creating a hazard to other motorists. This failure occurred …

I was informed to reference this code PE24029. 2021 5th Wheel - Grand Design Solitude 310GK. Frame cracks and separation. June 2025, contact made with Grand Design and they approved for us to obtain a welder. We did. It did not correct the issue and we contacted Grand Design again. Our Unit has been in the repair shop since December10, 2025. Back and forth emails with Grand Design. Sides need to be taken off to get to frame issues and make a repair.
