Sure would be interesting to see a small truck version for the single engine. A smaller truck could even be more simple in design. Maybe a smaller backseat area, still I love the big truck too! I'm sure it will happen some time.
Being able to plug in a solar panel directly would be great too! Perhaps a solar solution under the bed cover? Well the sky is the limit and our imagination is captured ...if your listening Tesla (aka Elon, Franz, and co.)
