One of these days I will review a Unimog. Mogs rule!
I grew up in Northern Ontario and this is what "Off Road" looked like:The only thing we could drive on was logging roads which ranged from a skidder track to a gravel haul road. Full size 4x4's ruled.
What struck me is all these are rather large vehicles. Usually going down a trail a smaller vehicle can be very helpful. A beefed up Tracker or Niva might work better than a jumbo 4x4.
