Issue Description: On multiple occasions during travel, cargo doors and the main entry door have opened while the vehicle is in motion. We have been fortunate to notice the doors flying open, allowing us to quickly stop before losing any cargo. Cargo Risk: These compartments carry cargo. When the door flies open, there is a significant risk of cargo flying out of the vehicle. This creates a hazard for oncoming motorists, either through airborne cargo or cargo on the roadway. Evidence of Problems: Missing sidewall screws in front storage. Loose sidewall screws. Bulging on the frame on both edges adjacent to the pin box. Poor alignment of cargo door and entry door. Kitchen slide is binding, preventing proper opening and closing Symptoms / concerns of excessive frame flex
