I agree that sitting on the side of the road for hours is no fun, and one of those things you'll try not to repeat.
Regarding the OP question about wanting to carry a compressor because RV didn't come with a spare, on a smaller motorhome like an Axis/Vegas with 16-inch tires I would personally prefer a spare over a compressor -- if I had to choose between the two. I would apply the cost, space, and weight of a compressor towards a spare.
When I got stuck on side of road in a large Class C with 16-inch tires, a compressor wouldn't have helped because it was a tire failure, not a slow leak. And at the time I felt comfortable replacing the tire; which is key. If I wasn't comfortable replacing tire myself then spare is of less value. It's one of the many reasons I like smaller RVs. On big rigs tires are too heavy for most of us to change.
