How young is too young to move in with your boyfriend?

I'm just curious what y'all ladies think, because my boyfriend and I have been talking about this a bit! We're both 19, been together since we were just 15. We just finished our freshman year of college and we know we want to live together (maybe just for a summer to start out and see how it goes), but just don't know when. We both have two part-time summer jobs and one part-time school year job so we work hard and could definitely support it financially if we start saving. Is 20 too young to try out living together? It'd be next summer after we finish our sophomore year of college. What age do people normally move in with their partners? For us it definitely wouldn't be for good, I think we just want a temporary trial to see how we'd do for the (maybe) future! ☺️ I'm not sure what either of our parents would think of it (I think mine would be pretty against it) so I just wanted to get some opinions!
