We have a 2018 BC 3650RL. Have only been on one trip to Lake Texhoma. Our sound on TV sounds like it is not going thru the sound bar. It sounds like TV speakers only. Sound is coming from behind TV and can't see a sound bar at all. We have tried different inputs with no difference in sound. We tried a DVD from the Furrion Radio and it sounded better. I am wondering if they wired the TV up to the sound bar? Have not had a chance to take TV off the wall to see. Also our sound cuts in and out. I emailed Furrion and they said this will happen with a week signal. I was using a direct tv swim dish and all numbers on 102 was in the 80's and 90's. It also cut out when on over the air antenna. Will Investigate further when I have time. Will be retiring soon so will have lots of time.
By the way, We love this RV. Lots of storage, We were concerned that it wouldn't stay cool in the Oklahoma heat but it does a fair job, when we can keep the grand kids from going in and out the door. The ceiling fan does not move very much air but we bought a dyson fan that moves lots of air and it helps. We had a raddle in AC duct in bedroom that was very loud when trying to sleep but I got up on the roof to look at the AC and some how it went away. Didn't do anything, It just quit. This unit has the new duct system instead of the old foam duct that they had for years.
