Yup Hafflingers are the ultimate off road vehicle ! With a serious set of tyres (preferably off a dumper truck) they will go virtually anywhere, and when they get stuck, you just pick em up and shift them.
The Pinzgauer is like its big brother, and ideal for a camper conversion IMO.
Then the big daddy the Unimog - but I certainly wouldn't want to try and fix one if it broke !
Missing from this list is of course the Russian Zil truck - absolutely fantastic bit of indestructible kit check out

available on ebay as ever.....
I watched Ewan McGregor and Charlie Waite doing "the long way around" motorbiking around the world. They used BMW touring bikes -top kit as KTM blew them out (fools). But still ended up crossing the Siberian rivers in the back of the Zil trucks.
