Update: Below is a video of the RMH running with the divider plate separating the front and rear sections of the firebox. This set-up was working ok but when we would load the back section with wood while the divider plate was in, it had the tendency to smoke back into the room. When the wood loaded in the rear section came up to temperature it would burn really well. So well in fact that it destroyed the divider plate in a few burns.
Below are 2 videos of the RMH in action without the divider plate. The audio in the video is mostly redundant. One video shows the the fire just being started and the other video shows the fire after a few hours. This set up using the lids without the divider plate works really well for my needs. Very minimal smoke back, only when loading the rear section.
Below is 1 short video from the top of the firebox as the fire is built.
