What immediately comes to mind is to fill it with expanding foam, but putting that stuff into a constrained space could be risky. The foam can exert a pretty powerful force and bulging out the wall is possible. Does anyone have experience insulating a panel truck?

I'm guessing I might be the only on on our forum with exactly that kind of experience. I helped my Dad insulate the cavities of his new one ton panel which we converted into a Suburban in 1965. We used loose fill styrofoam beads poured in through the taillight openings. Dad made a pusher with a disc screwed onto the end of a long dowel to push the beads to the front of the cavities. A little messy, but it worked. I think you'd be asking for trouble using expanding foam.
