I once brought home a Kangaroo standing up in the backseat of a Lebaron convertible with the front seats pushed all the way forward. Can't believe it worked.
When I used to have my flatbed I could get 7 games on it by myself. I only needed help for the 8th game because that one had to be lifted into place while still standing up. Btw, thanks to the many strangers who have helped me get that last game on at various auctions and picking sites.
Speaking of monitors. I once wheeled a half stripped Asteroids to Sega Star Trek conversion to the flatbed, laid it down, stood it up, muscled it into place, drove home 400 miles, laid it down, pulled it off, stood it up, wheeled it somewhere else and only later discovered that the Color Vector monitor in the thing wasn't hooked up or bolted down, and it didn't even have any front glass on it, so the monitor could have fallen out at any time.
