Algodoo

This is a work in progress know that before you download it. The reason I am uploading it is that I need help with it. The problems are that the suspension breaks frequently, and there are other problems with the suspension too. The wheels also get stuck to the ground often. It's not useless though. It absorbs bumps very well when it isn't stuck.
(It's a panel truck because it is slow and needs improvement.)
If you find things that could be improved on please leave comments or upload it with the changes, and let me know.
