Growing up in Northern California, we lived right at the base of the Sierra Nevada Mountains.  My Dad aways had a 2wd Ford Ranger F250, Camper Special and a Cabover Camper.  In the winter, we drove to the Snow Line, in the Summer we launched our Boat.  Remember 250 Hp, 4:10 gears and Rear Limited Slip. 
Now, Ford Trucks have 400 Hp, 4:30 gears and a Rear Locker.  Also, todays public Roads, Campgrounds and Boat Launches are so much better.  You'll find today's 2wd's performance amassing.  Either choice you make, it still takes a little common sense ..
