Road Trip Advice?

Hi! We're getting ready to go to Pennsylvania from NY on Thursday, or LO (11mo) second long distance trip. Last time she was still just on her bottle so it was easy. But now she rarely wants her bottle and DEMANDS finger foods for meals/ snacks and juice/ water when she's thirsty. Trip is about 5 hours and we have planned 2 rest stops at about about 1.5 hr intervals. My friend is going with me so we're planning on her sitting in the back with the baby while I drive. Any idea on snacks/meals that are easy transport for the ride?
