Ditto to all the comments and now my 2 cents:
We use our 4 x 4 like the others, once in a while off the road when putting trailer into a space, driving control is increased when driving on a dirt or gravel road, snow possibilities when traveling for safety, and a couple times I have been in places where backing up a hill to park into spot without 4 wheel drive, I don't think I would have made it in. This happened a few times in campgrounds and rv park. for me, I won't be without!!! Good Luck & be Safe ! ! !
