Hi I'm thinking about buying a D40 to tow my caravan. I like the towing capacity of 3 ton but am worried the 4cylinder diesel being able to pull up the hills etc. Also will there be a substancial fuel saving? My wife is concerned about it being a rough vehicle to ride in. The other choice is a Pathfinder if it's smoother. I joined this forum to read about the Navara and the Pathfinder as I like these vehicles. I currently use a Ford Territory for towing, expensive for fuel but lovely to ride in. Do you think I'm due for a change?
