There is an outer layer on the bag. That is what you see cracking, not the actual bag itself. No worry, you will wear out the coach before you need to replace an air bag. Unless one gets damaged of course.
Piece of advise about Alaska. To save damage on the coach, there is no reason to drive over 50MPH. To protect the toad, the best thing is a underskirt. Several manufacturers, just Google RV underskirt.
