If you crawl under and look around near the tank you may find a small pie hanging down a few inches. It may have a shut off and that would be it. In some models I have seen the valve inside and near the tank.
An alternative way is to use the low point drain ( if you have one) near the water heater or water pump area but that would take a long while to drain.
Maybe call a couple dealers of RVs in your area and ask if they have any info on that model?
