Off-road ride in small replicas of KRAZ and KAMAZ trucks

It has long been known that not all heavy transport enthusiasts like it on a 1:1 scale. Some spend many hours trying to reproduce their favourite models as faithfully as possible in a smaller version. The effect of such efforts can be seen in the following video showing two truck models in conditions which, due to the size of the models, can be described as off-road. How did KAMAZ and KRAZ cope with the wilderness? See for yourself.
