Gene, that docking station is a nice idea. My new tv has a outlet for the 'blue plug" from a computer. I will have to think about that...
Burl, I like keeping the tv hidden, and this way I don't have to stress the door. As for your cement block, yes, there is some foam and other stuff up there. I did 2 things, I used 'Great Stuff' and silicone sealer-first I removed the headliner. Fed in as much silicone and in other places 'stuff' as I could get between the metal roof and the coach deck above, and then sent drywall screws right through the roof. Great deal less squeeks and rattles. I also have a 213 and love it despite the 'growing pains'. I like your idea about the shelving in the rear outdoor compartment. I find a small bit of water in mine at times, still can't figure out where from. I have an 05 also and haven't bothered to try and do 2 batteries because there just doesn't seem to be the room. Lemme know if you have success.
Marco...polo...marc...(sorry) anyway, welcome. We were in Italy for the last couple of weeks. Lots of B+'s there.
