Do you mean a Saturn IV-B? Those were the third stages of the Saturn V. If so, the complete Saturn V was displayed horizontally outdoors for quite a while. I was in the US in 2018 and stopped by KSC too see a Falcon 9 launch, by then the complete Saturn V was in a building.

If you mean just the Saturn IV (no B), that was the second stage of some early Saturn rocket. I don't know much about those or if one was ever on display.

Sorry about my typo. I meant Saturn V. If you watch the video in the parent article, you'll see James Burke walking around it with the VAB in the background.

I even remember visiting that Saturn V in Florida as a child!
