The NHTSA says it's been in contact with both Grand Design and Lippert, the frame manufacturer,

and that Grand Design believes that some frame flex

generally considered to be vertical movement in the upper deck area of the fifth wheel is normal.

says that per grand design, the frame flex is only occurring in the upper deck area of fifth

wheels and is resulting in cosmetic only defects, such as moving sidewalls, damage to cabinets,
