Hello,
Here we can show some of the best videos on the internet. Watch out, things may get dirty.
We have this little competition in our neighbourhood, called truck trial. Some great examples:
Extrem offroad - Truck TRIAL - Tatra 6X6 Ural 6X6
Extrem offroad truck 6x6 in mud - Truck trial
By the way, is this ok with forum rules? If not, please delete it.
Edit: In second video, i suppose they did get some extra differential damage.
