Camper van. Read before contacting

1988 FIAT DUCATO 2.8 TDI Swift Royale 590. Bought this on Done deal around June last year. Was sold to us as a NI camper van that would only cost €1500 to transfer to ROI plates, turns out was in NI a month or so brought in from England. So will cost around €3000. We have only used the camper a handful of times since purchase. Drives well, very comfortable. Our use case has now changed, so will not be worth the hassle or cost to get changed over.
