I can put a 1/3 Hanger Nine Pawnee in my like new 1976 Chevy Estate station wagon. I've had it since new when wife use to use it for boy scout troops and church kids.
I took it over as a plane huller and built wing racks above and goodness only knows what all is under the seats.
Keep your mini Van....your plane likes to ride in AC comfort instead of being beat to death in a darn hot trailer.
