The new generation of X'rs have different styled side view mirrows which helps to limit the blind spots, but it is still there! I still have to quickly turn my head to make sure there is nothing before changing lanes though.
Rear hatch loading not a problem, although I miss the X5's split trunk as we could always place stuff on the lower lid. 3M the color coded top portion of the bumper, otherwise you or your dogs might scratch it. Also, if your garage has a low roof, you'll need to decrease trunk opening size, which means that you will be leaning into the trunk space to avoid bashing your head.
Hope this helps, cheers!
