One of my TV sets is a car stereo with a little 1.5" b/w CRT. LOVE that thing...and it sits on a 12Vdc power supply hooked up to a real cheesy '80s EQ booster thing with the "spectrum analyzer" LEDs. It's CRT is likely the exact or similar as the little Panasonic TR sets....and I can't imagine having that in your DASH and watching it even when parked. It does have a GREAT am/fm tuner though....and a good running auto reverse cassette deck.
It's not quite a workbench, but still the same sort of setup. The headboard cabinet of the bed....and wired to four little bookshelf speakers
