If you get the latest update to the Fuse (2017.5) you should be OK. I have one of the first ones off of the line and they were 1-2 inches closer to the ground.
I have scraped the stairs going over a large speed bump. Going in to the area I went over the bump no problem, Going back out I scraped the stairs. Scraped the rear going out a raised driveway onto a crowned road. I went in fine as well but got caught coming out. If I had an extra 1/2 inch in either case I would have been golden so with the latest updates would have been fine.
As far as BLM or backyards. Backyards I would feel good enough. I am not sure what BLM areas you are going to. I have been in a car in several BLM areas and some would be fine and some would not. I think that if it is a place where you would feel good taking a car you would be good. If it a place you would want a jeep than not so much. Our old mini-van had much less ground clearance
Hope this helps
