the suspension is barely loaded, I'm guessing AI or Art Vehicle and that's all a shell. I owned a work truck with an 8 foot bed and when it was loaded the tire would be way up in the wheel well more. Could be some super suspension but my money is it's not really what we are seeing. The suspension being perfectly level with the ground makes me think AI as the vehicle is designed to be level with the rear loaded. With that front loaded down too the nose should be pitched down a bit.
