Airstream trailer

The iconic Airstream is a mini hotel on wheels. Most have gas burners, showers you can actually stand up in, and an ingenious amount of storage space. It's smooth to tow, with a retro interior that conjures up a first-class train cabin circa 1955.

A good starter model is the 16-foot Bambi Sport, which can be pulled by a midsize SUV (from $30,000 used).
