Styling was up-to-date with sharply formed edges and large rectangular headlights. The front bumper covered only the corners, allowing the grill to be much more prominent than normal. The roofline terminated behind the large door on each side. Above the rear waistline was a pair of side-hinged clamshell doors covering the entire rear section. An integrated roll bar terminated the bodywork and also formed a place for the clamshell doors to seal. The clamshell doors met each in the middle of the roof with no center support. When the doors were raised you could stretch a tent between them. Two adults could sleep in the tent section and another two adults could sleep on the front seats, which could fold down flat. Finally, the rear section included a full-width tailgate with a wind-down window nestled under the rear roll bar.
A fully working prototype in RHD was shown at the Tokyo Motor Show and reviewed in the August 1973 issue of Penthouse magazine. Toyota also printed a large number of a brochure for the USA market in order to gauge the market reaction. It was generally well-received but apparently not enough to put it into production. The brochure included sketches with the steering wheel clearly shown on the left-hand side but the photographs of the real vehicle hid the steering wheel – which was on the right-hand side.
