Peugeot Service Intervals

Does anybody know the recommended service intervals for Peugeot based motorhomes?  I have the service record booklet but there is no information about the frequency, neither in the documentation nor on the MyPeugeot website. I had the first service after two years and have just booked an MOT and service for the end of the third year. I was asked whether I wanted a full service or just a routine service (safety check and oil change). Also, there was a suggestion that every two years should be OK?

The warranty will not be an issue as it expires at the end of three years and the mileage is low so it would seem a bit pointless to have it serviced every year.
