Yes, you definitely can. In a current Dodge Caravan, I've hauled:

Two B/W DMD games at the same time (Judge Dredd slid in from the back and positions width-wise behind the front seats, and Fish Tales perpendicular in the back)

A DMD and an EM (Top Score EM body slid in from the side, Shaq Attaq slid in from the back, with Top Score head next to it.)

Revenge From Mars body, head, and SWEP1 kit (that was tight.)

Seeburg Model A jukebox (a BIG one) slid in the back, two EMs stacked on top of each other slid in from the side with heads behind them.

A Caravan is about the best "normal" vehicle you can have as a pin hauler.
