We just bought a 1989 Damon Escaper, Class C, 26' (Ford E-350 chassis, 460 cubic inch fuel injected engine). We need to register it in South Dakota and the unladen (or shipping) weight is needed for the registration. I don't see the placard inside any of the cabinets and the tag inside the driver's side door only has the Gross Vehicle Weight, which is not acceptable for the South Dakota process. Does anybody own this vehicle and have the information I need? Seems this vehicle is a bit rare and I can't find the info online YET. This is so frustrating! This info would also be on the original Certificate of Origin, which I don't have either.
