I would query that, I have an RDF sesaver R, the service cost was about right lasr year but next one is not due for 3 years. I have a seperate equipment pack attached to the raft with torches flares etc that means I do not rely on any of the stuff in the raft pack exepth the raft itself, this pack is checked anually and the equipment is of much better quality. Means I done worry to much about service intervals.
