Just picked up the special edition 300 series tonight. I noticed the knobs turn and are not true...as u turn them they end up rubbing against the steel front. Did I explain that good enough. I am not familiar with these fancy new grills just the older ones. Is this a knob issue or was too much pressure put on the manifold or knob stems by the movers and bent something? Surely this is a common thing. I will revisit the grill tomorrow.....just being lazy and askin u guys so i can sleep tonight
