Have owned for just over 2 years. I loved the idea of the grill when I bought it and it was great the first season. The second season it rusted so fast on the gas side and now is rusted completely through the back of the firebox, bottom pan, burner tubes, all tents and grates.  It has always been covered at night and during inclement weather and has been cleaned religiously.  The charcoal side moving parts no longer operate correctly and the charcoal pan has warped. For the price it should definitely last more than 2-3 years.  Time for a new grill!
