Elon Musk and Tesla have been quite mum in regards to the truck's details, but that seems to have changed. Elon Musk recently sent out a series of tweets that go into possible features and details of the truck. These tweets all point to a truck that will be exactly what we expected: a high-power electric pickup truck that will be full of bells and whistles.
One possible feature that another Twitter user propositioned and Mush harked on was the addition of a heavy-duty air compressor to run tools on. Musk says that the truck will have a Tesla pneumatic system that would just need a utility port to make it happen.
