Cover art for Run lyrics by Vampire Weekend

I think it's "change in rolls", like when people keep a change jar in their house. The girl has a stash of money ("but with her fund") and the guy is talking about how they could take the money and either elope or just get away from their day to day lives for a while. The "battered radio" thing almost makes me think they're taking a road trip. The only line that trips me up is "I could take two but I really couldn't ever know" Anyone know what it means?
