Thanks for the kind words and I hope my posts help some one else do theirs. I also noted on the Jensen head unit that zone A has another set of wires. I wonder if the DW is ready for more holes and more speakers in the living room area. I was thinking that another set of speakers further aft would be good for our son to lay in bed and hear the TV better.
It would make for a much longer fishing endeavor, but the new has worn off our 1 year old camper and the mods are really starting to kick in. LOL
