We purchased an older Scamp from a couple in Michigan and I brought it home.
We down to the Clerk's Office at the courthouse and they informed me that since the purchase was made out of state, from a private party, that the trailer had to be inspected before it could be registered and subsequently licensed. The provided the contact information for the inspector.
Nice gentleman that covers over half the state performing inspections. It took him almost a week call me back and another week before he could get here to complete the inspection. This was not a problem because we ended up completing a renovation project that took us over 14 months and included nearly a complete gut with exterior paint job. We camped when we could and worked when we couldn't, but it was two weeks before we had plates and were authorized to be on the road.
If the camper had come from a private party within the state or from a manufacturer, no inspection would have been required.
