Al Cottler found some pictures on the Iowa Boys website of a Silver Streak Travel Car Lodge Motor Home. These are located at http://iowaboys.com/9974silverstrkmh/9974.htm . It turns out that the unit is a Streamline, and one of the first ones at that, a 1964. I spoke with Sue Murphy of Iowa Boys, and they have no plans to sell the unit. Currently it is being rented out for the occasional movie, but is otherwise unused. Possibly, they will tear out the inside and redo the unit eventually.
The coach is 26' long, and has the engine in the middle of the unit. There is no passenger seat, but rather a sofa opposite and facing the driver. Behind the driver's seat is a wet bar.
