In this pic you can see the pipe and faucet from the tank on the roof coming down just to the left of the table. Must be for water as I doubt they would pipe anything else to the interior of the box. I'm thinking mobile Dentist's office perhaps? Please swish and spit! Any fittings in the floor for a drain?
Also, the spare tyre is stowed just as the spare on my C15 when I first purchased it. I was told by the previous owner that my CMP had a large box on the back that the owner before him used as a camper. He thought it was a wireless box but had no proof that it was. He removed it decades ago and it has since been thrown away. I do know that my truck was ex-Argentinian and that the frame had been lengthened approximately 30" in the past to C30 length.
