Hi Jeep4Two!! I'm a Jeeplover too. My TV is an '06 Commander Limited. Love it.
On the topic of the shelf behind the sofa-- it is primarily there to support the sofa back when it is set-up as a sofa. We always keep ours set up as the bed, and as you probably know too, the shelf is literally a pain in the butt, side, elbow, legs and knees while sleeping. I bought a 6 ft. length of pipe insulation to pop on the edge of the shelf to "soften" it, it's precut along the entire length, cost me a couple bucks at Lowe's. I picked the thickest and softest, dark grey, goes nicely with the interior(LOL!) I use this shelf to keep a bottled h2o nearby and a couple of very small fans angled across the sleeping area. Nothing else can really be "stored" there, I've seriously thought of removing it, just haven't done it tho....
