I think the two golf bags or the two strollers would have to go. Unless you rent/buy one of those top luggage carriers for the top.
I have a Town & Country, which is the same as a Caravan, and I have three large car seats in ours. There are two in the back, and because of their size, the third row can no longer seat three people, just the two car seats. My third large car seat is in one of the second-row Captain's Chairs, which means entering from that side of the van is a no-go. The kids enter through the other side that has a Captain's Chair folded into the floor.
So, you'd have to put your two Large car seats in the back, have two adults in the second-row and two adults in the front row. In the back, youd be likely to fit three large bags, and maybe the fourth. And the golf backs could be on the floor behind the second-row and under the kids feet. That leaves the strollers. How big are they? Really your only option would be to put them under the adult feet in the second row? But it would depend on the size. If you get a minivan with out captains chairs in the second row, you will not have as much room
