There are several levels of daily drivers or at least there is a difference between a rig that is driven to and from work and one that is capable of handling extended trips as well as trails.  Both my 85 truck and 89 4Runner have been driven from Washington State to Moab for a week of wheeling and the 4Runner made the trip to the Rubicon.  There's a special balance required to "comfortably" handle 70 mph all day still be capable of running the difficult trails.  The last trip back from Moab was done in a single shot with nothing but gas/food stops.
