The 18-foot聽 (from $32,500) is just short enough to fit聽inside a standard garage, but long enough to聽sleep four adults and high enough to stand in. Amenities include聽a shower, sink, stove, fridge, bunk-bed, and a full-size bed. Thanks to lightweight aluminum panels, the trailer only weighs聽2,300 pounds, so you don't need a聽full-size truck for towing.聽
