McZip, that's a nice paint job. With the right lower color, one might not have to paint the upper area at all. My '86 Blazer was light grey bottom and white on top, I got lots of complements on it.
TV box: I built mine with the idea of gaining storage as well. My original design had a bracket/shelf affair to hold the new flatscreen. I've since added a fold down hinge and 'flush' mount bracket. Now the tv folds up against the roof of the box when underway, and we store the remotes and 3 full size pillows in there. (DW likes pillows.)
