NHTSA Complaint #11557602 — 2022 GRAND DESIGN SOLITUDE

While towing on I-75 at 65 MPH, the driver's side front storage doors came open. These doors had been shut, locked, and checked before departing. They were secured again and remained closed at a lower speed. Examination revealed two design flaws. First, they are side-opening overlapping doors. With an overlapping (rearward) door facing forward, this allows the slipstream to enter the gap putting strain on the two retaining locks. The second is on the two cabinet cam locks for the forward door. The throws for both are short with the upper barely making contact with the frame of the opening. vibration causes this one to come loose opening the gap for even more slipstream penetration. Solution reorient doors so overlapping is facing rearward, and put longer throws on cam latches. I replaced the short one with a longer one that had to be molded to fit, the forward door is much more secure now. This problem has been reported by other owners of this model 390RK on Facebook.
