A long time ago, someone told me to always keep a spare air line set and spare trailer 7 pole electrical cable. Now I know why. These red and blue air hoses, plus the green electric trailer cable are under a lot of stress and can break, causing you to have to stop dead in your tracks. Without a spare, you're stuck with whatever they carry at the truck stops. And those aren't the best, but they are the most expensive.
BE PREPARED!
