Had the fireplace front cover (glass) fall off and shatter while driving down the road. This cover is “locked” into place, and needs to be physically lifted off so this does not happen. Has anyone had this happen? I was going to call Grand Design and tell them that they should send me a new one at no cost. It is at a dealer right now being looked at. To make matters worse one of the pieces of broken glass, that we missed got under one of the slide outs and ripped the flooring!
