I have wanted this as long as I have drive T-series. There are lot of semis used daily on off-road conditions, some build RV's that can go anywhere that cost big money and those are based on 6x6 or 4x4 semis. Some go adventure riding on adventure motorcycles, some go adventure off-roading with RV's, then some guys have to off-road to haul logs, harvesters etc. There is quite variety really.
