When I registered my RT in Ohio, the DMV started to register it as a van since that's what the VIN tells them it is. I insisted it be registered as a MH and took the clerk out to see the vehicle. Once she looked inside she agreed and registered it as a Roadtrek MH. If you're in an accident and have an insurance claim against another driver and insurance company, you want it registered as a MH, otherwise any damage to RV parts (furnace, water heater, refrigerator) could be denied.
