It all depends on where you are going.
2 trucks ago I couldn't climb a hill on a logging road in a 2WD and that sent me over the edge to buy a 4WD. When I replaced that truck with the Colorado I stayed with a 4WD. Although I rarely will have a need for it these days, I like having the option and I don't mind the expense.
That being said: You know the conditions you expect to be in better than we do. The G-80 automatic locker will do the same thing your previous truck did. Between that and decent tires you can get through most situations.
