Hi All - first post! I have a 2015 Big Country 3070 RE and the bulbs on the Greystone SF103-35 fireplace need to be replaced. Also the inside needs to be cleaned out. I can’t for the life of me figure out how to do this without taking the entire rv apart. The fireplace is surrounded by a molded plastic brick wall and behind it is a wooden frame all nailed, screwed and bolted together. It’s like a fortress! I can’t remove the molded plastic brick and I can’t get behind it because of this frame construction. There are no screws in the front and nothing to take off that I can see. Please help - I appreciate all your responses. Thanks!
