Just looking at the body... while a Unibody design will work for city usage, I don't see this working for anyone that does any towing, hauling significant weight, or frequent off-roading. There's a reason the truck manufactures have stuck with body-over-frame, you separate the "hold the people" concerns from the "hold the weight" concerns to make a more durable product. Essentially, if you're using it as a car, it'll make a great car, but using it as a truck will inevitably lead to failure. If you don't believe me, ask any 4x4 Offroader, or watch: https://www.youtube.com/watch?v=TKMQjm7i2Jw
Speaking of reliability, the American truck market is _hyper competitive_ and that is one of the main reasons people buy the vehicles: they just don't break down. I think there's a great opportunity for truck makers here: an electric truck has far less things to break. A generation leap in reliability could be achieved. I think GM and the new Hummer has the best chance of breaking into the market in this regard.
