The campers I have seen all have some type of stereo in them, so I would say it is odd that your camper does not. Should be fine to use that power wire. If you're installing a stereo that drives a lot of watts, then you could run into a situation where that wire cannot support that load without a big voltage drop. My hunch is that this won't be a problem though. Keep in mind that you are probably adding a small parasitic load to your 12V system for the stereo's clocks and memory that may or may not matter depending on your storage practices.
