Not into bubble bursting, however:
1) there's no slides on that cover coach
2) theres no tag axle, therefore its 40' or less
3) quick visual measurement, theres not enough room to fit that car or the video car under there. Note where the floor line is, now add up car, store mech. And then lift mecanism! Impossible...
The one I saw was a Mercedes 450 SL., I believe this is really Internet lore.
