 This design provided space for a large child's cot overhead, and on later models, the poptop was further enlarged to fit a full bed large enough for two adults.The add-on side tent underwent a complete redesign.The new model (referred to in publicity materials as an "Add-a-Room" tent or a "Motent") superficially resembles the late Split-windshield's framed tent in general shape and colors, but is otherwise quite different.
