What is the service interval for a 2007 Ducato 130 Multijet please?

I have a Benimar Perseo motorhome based on this chassis. Previous owners seem to have had oil changed every 15,000 km and there was a ticket saying next change is due at 45,000 km.

But Fiat Service manual seems to say first service is at 45,000 km. Is that correct?

P.S. Unlike some motorhomes it does not sit in the drive most of the year but is used for trips at least twice per month (except July and August!)

Yes, Handbook (p 191) says change engine oil and filter every 45000 km.
Surely you would be hard pressed to do that many km in 12 months?
In which case, changing every 12 months would be wise.
