Here's a summary:
It's going to be a big truck.
Musk said that it will feature a step that will lower to step into the truck and he said that Andre the Giant will be able to fit in the driver's seat.
The Tesla Truck is going to be a 6-seater.
It's going to have an option for 400 to 500 miles of range "maybe higher"
Musk previously said that platforms like the Model S and Model X would probably be capped at 125 kWh of energy capacity, but he said that the truck platform will offer an opportunity for a much bigger battery pack.
Dual-motor, all-wheel-drive powertrain with dynamic suspension will be standard on the truck.
The truck will have a 240-volt connection for heavy-duty tools and even an air compressor to run air tools.
The second part was a suggestion that Musk liked since the truck will already have a pneumatic system for the air suspension.
