Truck weights about 4280lbs with out driver, I already have some race seats and a lift off hood so it might weight less even after the cage its done.

I just know that when I had it at 7psi and then I would put 12psi it would make a huge difference, we'll see what it does with 15psi and if Allen wants to try 18psi he is welcome to do so.
