MudRunner

Your main objective is to collect 4 logs at 3 different spots. The 3 bonus objectives are:
Don't damage your vehicle or any other vehicle
There aren't may areas where you can actually damage your truck. I suppose if you slammed a log into it hard enough with the crane it might cause some damage, but in my experience, the truck can handle some hits from the log. As for other vehicles, there is a parked car you'll want to look out for when backing up.
Don't break any wooden fences
The driveways you back into have wooden fences all around them. You can hit some fences, and usually they will just fall over. Only when you hit them hard enough or drive over one will it break and fail the objective.
Don't use the differential lock
Just don't hit and you should be good. When driving down the road to the final destination, stay directly in the middle of the road and you'll get right through it.
