Leave it as it is and just drive it as they've been driven all these years. You asked and that's my suggestion. There is no reason a person can't daily drive one just as they are. I do, except on salty roads (
). If you want to do all that, that's fine. We all do what we want to our trucks. Just saying you don't "have to" do any of that.
There are only certain times you may need 4wd in and out driving on the road. When those times occur you just lock the hubs in and hit the road in 2wd till you hit a bad spot. You have shift-on-the-fly. lever/button, what's the difference?
