I actually did want a lighter, 2 Wheel Drive Cybertruck (for $40,000). The "Long Range" trim was close. But it was actually $70k not the $60k they were saying.

Get rid of the touchscreen and the four-wheel-drive steering and the electrical flush door handles, the hatch thing in the back, smaller wheels, any other electronic features like 120v inverters, etc. solid rear axel would be nice but that would be a major redesign.

Swap "solid rear axle" with "De Dion axle" and your description fits the Slate truck pretty well.

You should look at the Slate...

Slate truck or telo trucks could be the move
