Just a short update... Had a pretty significant maintenance month. in the past 30 days, I have had to replace the engine starter, replace the back door lockset (the "striker(?)" broke so that pulling the handle yielded nothing - I had to cut the metal away on the device with a dremel and work out the material with a screwdriver in order to open the door - installation was simple, but expensive after that - $227 for both sides of the lockset overnighted - there were none in San Antonio), refer just went out. I have the CSP coverage, which will pay for a rebuilt sealed unit to be installed for $100. I didn't use CSP for the starter and door, as I use the motorhome almost daily to drive, and didn't want to put it out of commission, waiting for someone else to do the work - also, they wouldn't have paid for the overnight on the lockset anyway). I am at 89K miles now. If I keep this unit more than one more year, I am looking at some serious renovation of the interior - though it is still doing okay (no tears - just worn). If I do that, I will probably look at someone doing some reengineering on the slide, so I can eliminate the leaking once and for all (open or closed). Overall, ownership of this unit has been a satisfying experience. I really do believe the assertion of Chevy that the 8.1 is good for 200K miles. Also, though I have read some nightmares about the smaller ONANs, and had misgivings about the lack of a low oil shutoff, or oil filter, I have used the H--- out of that unit, with virtually no problems for 5 summers! The cost of ownership for 100K miles will actually be minimal. When I get to that point in the next year, I will summarize what I have spent for preventive and corrective maintenance.
