Cool designs, and trailers I'd love to admire in person

On the road in the mid 1930's, from Beirut to Baghdad, by way of Damascus, reminded me of the 1937 D-35 Jungle Caravan of Commander Gatti
The above was designed by Brooks Stevens, its a 1936 Zephyr Land Yacht

The above is a Curtiss Aerocar trailer. I'd like to see a photo of the rig in the trunk of the car towing it. It reminded me of

1932 Arrow Plane in a museum in Mesa Arizona
