lostdog and barmcd,
Not giving you heat, but for us, that was the perfect arrangement. When you lean back on the sofas, viewing the TV is perfectly natural. We have four kids with us and our dual sofa layout gave us the sleeping space we need, plus plenty of indoor seating space to watch movies on rainy nights. No problem seeing the TV from the couches or the dinette. Even from the rear facing dinette you can see the reflection of the TV in the mirror. If there were just two of us, then maybe a different arrangement would work, but we needed the sleeping and living space. We also have (almost) plenty of closet space as we have closets where a lot of the new rigs put bunks. That, in my opinion, wouldn't be my choice as I don't want the kids a paper-thin wall away from the mommy-daddy sleeping space. Much better to have them all up front.
I've seen a number of rigs with the TV in the middle, but for many of them, any time anyone gets up, they walk in front of the viewing area. In some cases, anyone working in the kitchen area would constantly be in the way of those watching TV. Again, maybe not too bad with a couple, but with a larger family, not a good solution.
We also have shelves on either side of our queen bed.
Our floorplan is what sold us on our rig. The dual sofa layout is rare in a gas motorhome and ours was being phased out when we bought it in 2004. Might've gotten the last GBM with that floorplan for all we know.
