I have the 2011 312BH and use the outdoor kitchen almost every weekend as we kept it at an extended stay site in Galveston, TX. The only issue I had was where the strut attached. The stud on the bracket was pressed in (like a pop rivet) and came out after a few uses.
I drilled out this fitting and replace with one that I could bolt in and have not had any issues since. I always kept a hand on the door when opening and when I close, I use equal pressure pulling down on the door. Has worked for us.
I also check each screw periodically to insure they are tight.
