I just picked up 2 pins (heads attached) from Virginia with a rented T&C and had no problem fitting them in. You have to load them in through the back hatch as they won't fit through the side doors due to the latches. Make sure you lay something on the floor to avoid the seat clasps or be real careful while sliding the pins in to prevent cabinet damage.
I laid some cardboard along the floor and used another piece under the cabinet to make sliding the game in/out a breeze making sure to avoid/lift over the seat clasps. 1st pin I put sideways (Door to Door) and the 2nd just slid in with room to spare. could easily fit a 3rd pin inside if you detach the heads of pin 2 & 3 and lay them sideways in the back. Would have to have extra padding for the seat clasps though, just a warning.
Caravan / T & C's provide a very nice ride and get ok gas mileage to boot. I got an average of 25.2MPH from MI - VA and back.
