I found a Samsung soundbar with integrated woofer on sale, so I bought it and a bluetooth transceiver as recommended above. I couldn’t get the transceiver to work well. The power wire was too short. Instructions were a bunch of drawings and generally unintelligible, so I returned it.
I had looked at various ways to mount the soundbar—under the cabinet opposite the dinette and TV, over the passenger window, sitting on the window ledge behind the sofa, but unless I threaded wires from the TV across the cabin, it had to go on the dinette leaning against the wall and under the TV. That worked fine and the sound was not that close to us when we eat, and certainty better than the TV speakers. The places to attach the soundbar were not good for mounting under a cabinet and if on a wall, it was engineered to fall off after you go over a bump.
I also ordered a HDMI splitter for 2 in—DVD player and satellite receiver—with a remote to change them. I can send a movie to one TV and the satellite TV to a different one. I decided the work of unplugging cables and replugging cables was something I could do without since the HDMI splitter that came with the MH one had only one input.
Someday soon, I have to set up the satellite receiver and contact Dish to turn it on. Our parking space next to the house is not a good one for satellite antenna, but I think I can just clear the roof of the house and MH. Parking is on the north side of the house and the satellites are east of south.
The sound system in the MH is goofy and poorly designed with cheap radios and few options. The dash radio needs to be on, it appears, to use the back up and turn options—there are cameras in the side mirrors that activate the TV screen when the turn signals are working. Have not tried that yet. When I drove it home I could see along the sides in the mirrors, so I am unsure the cameras add much. It makes you look at the radio and not outside—if I can’t see along the side of the MH all I need is a concave mirror that will attach to the OEM mirror.
Note how many things are poorly engineered—hard to hang the soundbar, hard to understand the bluetooth transceiver instructions and short power cable, MH sound systems, side mirror camera system. These things come from China, S. Korea and the US, so engineering is bad everywhere for consumer goods.
