yes - we had a 2011 HW277 and had our front wall flex out when the front bed was extended. It flexed enough so the door had trouble fitting properly and the tenting would not reach the door. We had a bubble level on the side wall - the bubble showed level when we set up, but as soon as we pulled the bed out, the bubble would move showing the flexing and the travel door would not shut. We used cargo bars to support the bed until we could get it to a repair shop over the winter. They put extra bracing in it, it helped but was not a complete fix and they proposed more work for alot more money. I talked to Rockwood about the issue, sent them pictures. They recommended a different place to take it for repair and depending on what was wrong - they "may" help with the cost. As the area had gotten wet a couple of times from an issue with the gray tank - I felt that they would blame the flexing on water damage and not pony up any money, so I no longer wanted to deal with it and we traded it in.
