Yes, based on a Toyota Van! After answering questions for a while, it occurred to me that this might actually be a 4WD Toyota Van. But that would be crazy.
I figured the Porsche and Subaru questions, assumed the engine was in the rear. If not there, it would probably have to be under the driver seat, like in a Toyota Van.
LOCKED for RayTheRat to figure out what name this truck was given.
