Of the parts listed, the starter is the only one that I would consider having in the coach as it is something I could swap out without too much drama. However, the other items are a bit more involved to replace & I wouldn't want to do that on the road. Besides, as the others have said, it is easy enough to get the other items anywhere -- AND -- the other parts usually don't fail all at once, so you will have some warning . . .

I bought a new 39MT starter off ebay for $230.
