Hey Gene, that mount shown on your last post looks like the best. The trouble with so many of those paralellogram brackets is stability and ability to hold weight. I plan to do a similar job to ours like Burl, but I will mount the tv directly to the cabinet door hopefully in a manner that will not allow movement. I was thinking of a bottom hinged door, probably using a substantial piano hinge, and the LCD would be mounted to the back(interior) of the door, so it would fold up into the cabinet when not in use. I still have to figure out the head bump factor tho'.
As for your battery tray, Burl, is it made of steel? If so, the best thing is a full renovation if it's still in good shape. I would remove it, treat it liberally with baking soda, get it thoroughly dry and use a few coats of a rustproof paint. I did that with my '85 LandCruiser and it held up well for as long as I had it.
It's real good seeing the regulars still here! Can't wait to get our big baby on the road again!!
