We just did ours about 3 months ago. the mufflers run under the beds, we took the dresser (under the rear escape hatch) out and saved the sliding drawers and the face of the dresser, relocated it to the port side using the end of the closet as one side, and reinstalled the dresser face the sliding drawers. we built a bed frame to fit a queen size from finished plywood turned across (port to stbd) putting the head against the stbd muffler box with part of one side butting against the bathroom wall (maybe 14"). At the foot end of the bed we were able to install all the drawers (except the map drawer). We can walk around both sides of the bed. we installed house flooring and put a transitional piece where the bathroom door is (did not floor the bathroom). We used 1/8" finished to cover the remaining top and sides of the muffler boxes. stained all of it. I had strips of cherry cut the same width as the existing side (bow to stern) boards and installed across the aft bhd (where the dresser originally was). stained everything and are putting coats of polyurethane, haven't finished that yet. we bought a "bed in a box" mattress, love it. This way open the box in the stateroom and you don't have to drag a big mattress thru the boat. Let me know if I can answer any questions.
