moving in together?

Hey guys, so I've been dating my boyfriend for about a year now. We're in a long distance relationship. We're both 19. We've had conversations about Our future together. I can really see us moving in together in the future- we get along great, we've visited each other. Soon, we'll be going on a road trip when he comes to visit me. I was wondering- when would be the right time? I'm taking a break from college, but I was thinking I should finish before then. What do you guys think? When's the best time, how do I know?
