I had my first experience with an overnight sleeper train last week while traveling from Hue to Hanoi, Vietnam. Let me tell you, I thought I was traveling in style...and then I saw these jungle yachts. These incredible beasts of a trailer were used by Italian explorer Attilio Gatti during several of his exhibitions to British East Africa in the 1930's. Gatti's trailers were luxury apartments on wheels. They had air conditioning, electricity, bedrooms, and a photo lab...to name a few of their amenities.
