Suspension still exhibits "jelly effect" when under a heavy load.

For example, when you put the cistern full of fuel on a truck & drive. The wheels wobble like they will break off, especially the front wheels. Some trucks exhibit more than others. Royal & Transtar are especially bad.

BTW, I'm not trying to spam the forum, but you said one bug per topic.

The fuel cistern is way to heavy, specially compared to the trailers and the CAT fuel tank.
