Has anyone got a large booster seat (the kind with a back and full harness) AND an infant car seat in the back seat of their 80? Can you fit another person in between the seats? I would like to see some photos of various configurations of child seats and other passengers fitting in the truck, if anyone would have such a thing. Both my boys (4y.o. and 2 months) are very tall so I have the biggest of both of these types of seats. Thank you.
