You want proof..........I will give you proof, when I go out there in the truck next week I will take video on my phone and try to upload it to the pc, if not I will send it to a member who can.
I am going out there in the car, I will take video of this as well, and then if some members are still not convinced i shall organise a cruise.
i don't just want a video of your car rolling down a hill i want you to get some measurements with something, level, plumb line, dumpy level, council gradient tables, whatever, something that proves to me it is an uphill slope in the direction of your vehicle moving
