Trailer, Get Your Kicks!: The Time Travel Trailer, Book 3 (Unabridged‪)‬

Lynne McBriar swore her vintage trailer would stay in a museum where it would be safe from further time travel. But when a museum in Texas wants to borrow it, she determines that she must deliver it herself. Her husband Kurt convinces her to take it along Route 66 for research he is doing. What starts out as a family vacation soon turns deadly. 

Travel can be dangerous any time, but when your trip involves the Time Travel Trailer, who knows where (or when) you will end up? The family encounters early restaurants and motels along the Mother Road and even runs into a little romance.
