Towing capacities aren't realistic, completely unachievable

If your in an accident and someone decides to sue you, whether you were towing 10,000 lbs or 12,000 lbs is never going to come up in the discussion. It's not realistic to try and prove to a jury (who knows nothing about towing, weights, or why it matters) how much the rear axle of the truck weighed at the scene of the accident 3 years ago, rather then you simply failed to stop in time.
