Mike, don't know if you have solved your speaker issue yet or not. We have a 2012 Melbourne 29D with a Jensen TV. I found out for the overhead speakers to work properly you have to set the TV to AV1. This is performed by using the TV remote on my coach. Hope this helps
Phelps, Wisconsin wasn't any better. When the wind would died down the mosquitoes came out and we headed in! Clip on contraptions, I think actually brought more out, sprays didn't seem to stop them.
