Over the last six years we have averaged a little over $817/ year on scheduled maintenance for our DP. I don't do any of it but pay someone else to do it all. It varies quite a bit from year to year from 1,573 the first year when we had everything done after buying the coach used to around 535 on years when little gets done but oil, gas/oil filters, lube and maybe a hose or belt. These numbers also include scheduled maintenance on the diesel generator. The transmission fluid and filter changes itself adds about 430 to the usual numbers.
