I have almost no knowledge of patent law, but calling this a troll case seems a bit naive. If it comes down to market confusion, than probably this won't stick, because as mrw34 said - nobody buys a truck for it's look, or at least no serious share of the electric semi truck market I think. But if the major deciding issue in a patent case is whether or not a feature of a patented product infringes on another feautre of a patented product - then this could very well be serious.
