Must be another outlet somewhere I would think. Maybe in an outside storage compartment?
You could call Thor warranty division and ask them. Also ask them for the schematics for the van. That should include the electrical, plumbing, LP gas (if it has it) etc.

Make sure you give them the last 4 of the VIN number.
Maybe not totally related but I found this that is interesting.
